RAxML
There are two versions of RAxML installed in /apps/eb/RAxML. Which one you use depends on what sort of work you are doing.
From https://cme.h-its.org/exelixis/resource/download/NewManual.pdf
The MPI version is for executing really large production runs (i.e. 100 or 1,000 bootstraps) on a Linux cluster. You can also perform multiple inferences on larger datasets in parallel to find a best known ML tree for your dataset. Finally, the rapid BS algorithm and the associated ML search have also been parallelized with MPI.
Normally, you would expect a parallel program to become faster as you increase the number of cores/processors you are using. This is however not generally true. For recommendations on how many threads to use, see page 5 in the manual linked above.
To use the non MPI version of RaxML, please first load the module with
module load RAxML/8.2.11-foss-2019b-pthreads-sse
Keep in mind that because this version doesn't use MPI, the job can not be run on multiple nodes.
Running the hybrid MPI version:
To use the hybrid MPI version of RaxML, please first load the module with
module load RAxML/8.2.12-intel-2019b-hybrid-avx2
Warning: Make sure to specify less than the exact number of CPUs available on your system via the -T option. If you start more threads than you have cores available, there will be a significant performance decrease. The --cpus-per-task option should also be set to match the -T value.
The current MPI version only works properly if you specify the # option, since it has been designed to do multiple inferences or rapid/standard BS (bootstrap) searches in parallel.
Note that this version was compiled with AVX2 optimization, which is not supported on the AMD Opteron nodes, but it is support on all nodes that have the EDR node feature. Therefore, please add the option --constraint=EDR, as shown in the sample job submission below, when using this version.
The example below will show how to set the -T and -# values. The name of the alignment data file in PHYLIP format is primates.phy.
Example of shell script (submpi.sh) to run the MPI version in the batch queue, using 32 MPI processes:
#!/bin/bash
#SBATCH --job-name=j_RAxML
#SBATCH --partition=batch
#SBATCH --mail-type=ALL
#SBATCH --mail-user=username@uga.edu
#SBATCH --ntasks=32
#SBATCH --cpus-per-task=2 #this needs to be the same as the -T option below!
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=16
#SBATCH --mem-per-cpu=2000mb
#SBATCH --time=08:00:00

for the MR-based bootstopping criteria. The recommended setting is 0.03.
DEFAULT: 0.03 (recommended empirically determined setting)
-c Specify number of distinct rate catgories for RAxML when model of rate heterogeneity
is set to CAT
Individual per-site rates are categorized into numberOfCategories rate
categories to accelerate computations.

-C Enable verbose output for the "-L" and "-f i" options. This will produce more, as well as more verbose output files
DEFAULT: OFF
-d start ML optimization from random starting tree
DEFAULT: OFF
-D ML search convergence criterion. This will break off ML searches if the relative
Robinson-Foulds distance between the trees obtained from two consecutive lazy SPR cycles
is smaller or equal to 1%. Usage recommended for very large datasets in terms of taxa.
On trees with more than 500 taxa this will yield execution time improvements of approximately 50%
While yielding only slightly worse trees.
DEFAULT: OFF
-e set model optimization precision in log likelihood units for final
optimization of tree topology
DEFAULT: 0.1 for models not using proportion of invariant sites estimate
0.001 for models using proportion of invariant sites estimate
-E specify an exclude file name, that contains a specification of alignment positions you wish to exclude.
Format is similar to Nexus, the file shall contain entries like "100-200 300-400", to exclude a
single column write, e.g., "100-100", if you use a mixed model, an appropriately adapted model file
will be written.
-f select algorithm:
"-f a": rapid Bootstrap analysis and search for best-scoring ML tree in one program run
"-f A": compute marginal ancestral states on a ROOTED reference tree provided with "-t"
"-f b": draw bipartition information on a tree provided with "-t" based on multiple trees
(e.g., from a bootstrap) in a file specified by "-z"
"-f B": optimize br-len scaler and other model parameters (GTR, alpha, etc.) on a tree provided with "-t".
The tree needs to contain branch lengths. The branch lengths will not be optimized, just scaled by a single common value.

It roots the tree by rooting it at the branch that best balances the subtree lengths
(sum over branches in the subtrees) of the left and right subtree.
A branch with an optimal balance does not always exist!
You need to specify the tree you want to root via "-t".
"-f j": generate a bunch of bootstrapped alignment files from an original alignemnt file.
You need to specify a seed with "-b" and the number of replicates with "-#"
"-f J": Compute SH-like support values on a given tree passed via "-t".
"-f k": Fix long branch lengths in partitioned data sets with missing data using the
branch length stealing algorithm.
This option only works in conjunction with "-t", "-M", and "-q".
It will print out a tree with shorter branch lengths, but having the same likelihood score.
"-f m": compare bipartitions between two bunches of trees passed via "-t" and "-z"
respectively. This will return the Pearson correlation between all bipartitions found
in the two tree files. A file called RAxML_bipartitionFrequencies.outpuFileName

"-f q": fast quartet calculator
"-f r": compute pairwise Robinson-Foulds (RF) distances between all pairs of trees in a tree file passed via "-z"
if the trees have node labales represented as integer support values the program will also compute two flavors of
the weighted Robinson-Foulds (WRF) distance
"-f R": compute all pairwise Robinson-Foulds (RF) distances between a large reference tree passed via "-t"
and many smaller trees (that must have a subset of the taxa of the large tree) passed via "-z".
This option is intended for checking the plausibility of very large phylogenies that can not be inspected
visually any more.

"-f w": compute ELW test on a bunch of trees passed via "-z"
The model parameters will be estimated on the first tree only!
"-f W": compute ELW test on a bunch of trees passed via "-z"
The model parameters will be re-estimated for each tree
"-f x": compute pair-wise ML distances, ML model parameters will be estimated on an MP
starting tree or a user-defined tree passed via "-t", only allowed for GAMMA-based
models of rate heterogeneity
"-f y": classify a bunch of environmental sequences into a reference tree using parsimony
you will need to start RAxML with a non-comprehensive reference tree and an alignment containing all sequences (reference + query)
DEFAULT for "-f": new rapid hill climbing
-F enable ML tree searches under CAT model for very large trees without switching to
GAMMA in the end (saves memory).
This option can also be used with the GAMMA models in order to avoid the thorough optimization
of the best-scoring ML tree in the end.
DEFAULT: OFF
-g specify the file name of a multifurcating constraint tree
this tree does not need to be comprehensive, i.e. must not contain all taxa
-G enable the ML-based evolutionary placement algorithm heuristics
by specifiyng a threshold value (fraction of insertion branches to be evaluated
using slow insertions under ML).
-h Display this help message.
-H Disable pattern compression.
DEFAULT: ON
-i Initial rearrangement setting for the subsequent application of topological
changes phase

"-I autoFC" for the frequency-based criterion
"-I autoMR" for the majority-rule consensus tree criterion
"-I autoMRE" for the extended majority-rule consensus tree criterion
"-I autoMRE_IGN" for metrics similar to MRE, but include bipartitions under the threshold whether they are compatible
or not. This emulates MRE but is faster to compute.
You also need to pass a tree file containg several bootstrap replicates via "-z"
-j Specifies that intermediate tree files shall be written to file during the standard ML and BS tree searches.
DEFAULT: OFF
-J Compute majority rule consensus tree with "-J MR" or extended majority rule consensus tree with "-J MRE"
or strict consensus tree with "-J STRICT". For a custom consensus threshold >= 50%, specify T_<NUM>, where 100 >= NUM >= 50.
Options "-J STRICT_DROP" and "-J MR_DROP" will execute an algorithm that identifies dropsets which contain
rogue taxa as proposed by Pattengale et al. in the paper "Uncovering hidden phylogenetic consensus".
You will also need to provide a tree file containing several UNROOTED trees via "-z"
-k Specifies that bootstrapped trees should be printed with branch lengths.
The bootstraps will run a bit longer, because model parameters will be optimized
at the end of each run under GAMMA or GAMMA+P-Invar respectively.
DEFAULT: OFF
-K Specify one of the multi-state substitution models (max 32 states) implemented in RAxML.
Available models are: ORDERED, MK, GTR
DEFAULT: GTR model
-L Compute consensus trees labelled by IC supports and the overall TC value as proposed in Salichos and Rokas 2013.
Compute a majority rule consensus tree with "-L MR" or an extended majority rule consensus tree with "-L MRE".
For a custom consensus threshold >= 50%, specify "-L T_<NUM>", where 100 >= NUM >= 50.
You will of course also need to provide a tree file containing several UNROOTED trees via "-z"!

Please note that for partitioned models you can in addition specify the per-gene AA model in
the partition file (see manual for details). Also note that if you estimate AA GTR parameters on a partitioned
dataset, they will be linked (estimated jointly) across all partitions to avoid over-parametrization
-M Switch on estimation of individual per-partition branch lengths. Only has effect when used in combination with "-q"
Branch lengths for individual partitions will be printed to separate files
A weighted average of the branch lengths is computed by using the respective partition lengths
DEFAULT: OFF
-n Specifies the name of the output file.
-o Specify the name of a single outgroup or a comma-separated list of outgroups, eg "-o Rat"
or "-o Rat,Mouse", in case that multiple outgroups are not monophyletic the first name
in the list will be selected as outgroup, don't leave spaces between taxon names!
-O Disable check for completely undetermined sequence in alignment.
The program will not exit with an error message when "-O" is specified.
DEFAULT: check enabled
-p Specify a random number seed for the parsimony inferences. This allows you to reproduce your results
and will help me debug the program.
-P Specify the file name of a user-defined AA (Protein) substitution model. This file must contain
420 entries, the first 400 being the AA substitution rates (this must be a symmetric matrix) and the
last 20 are the empirical base frequencies
-q Specify the file name which contains the assignment of models to alignment
partitions for multiple models of substitution. For the syntax of this file
please consult the manual.
-r Specify the file name of a binary constraint tree.
this tree does not need to be comprehensive, i.e. must not contain all taxa
-R Specify the file name of a binary model parameter file that has previously been generated
with RAxML using the -f e tree evaluation option. The file name should be:
RAxML_binaryModelParameters.runID
-s Specify the name of the alignment data file in PHYLIP format
-S Specify the name of a secondary structure file. The file can contain "." for
alignment columns that do not form part of a stem and characters "()<>[]{}" to define
stem regions and pseudoknots
-t Specify a user starting tree file name in Newick format
-T PTHREADS VERSION ONLY! Specify the number of threads you want to run.
Make sure to set "-T" to at most the number of CPUs you have on your machine,
otherwise, there will be a huge performance decrease!
-u use the median for the discrete approximation of the GAMMA model of rate heterogeneity
DEFAULT: OFF
-U Try to save memory by using SEV-based implementation for gap columns on large gappy alignments
The technique is described here: http://www.biomedcentral.com/1471-2105/12/470
This will only work for DNA and/or PROTEIN data and only with the SSE3 or AVX-vextorized version of the code.
-v Display version information
-V Disable rate heterogeneity among sites model and use one without rate heterogeneity instead.
Only works if you specify the CAT model of rate heterogeneity.
DEFAULT: use rate heterogeneity
-w FULL (!) path to the directory into which RAxML shall write its output files
DEFAULT: current directory
-W Sliding window size for leave-one-out site-specific placement bias algorithm
only effective when used in combination with "-f S"
DEFAULT: 100 sites
-x Specify an integer number (random seed) and turn on rapid bootstrapping
CAUTION: unlike in version 7.0.4 RAxML will conduct rapid BS replicates under
the model of rate heterogeneity you specified via "-m" and not by default under CAT
-X Same as the "-y" option below, however the parsimony search is more superficial.
RAxML will only do a randomized stepwise addition order parsimony tree reconstruction
without performing any additional SPRs.
This may be helpful for very broad whole-genome datasets, since this can generate topologically
more different starting trees.
DEFAULT: OFF
-y If you want to only compute a parsimony starting tree with RAxML specify "-y",
the program will exit after computation of the starting tree
DEFAULT: OFF
-Y Pass a quartet grouping file name defining four groups from which to draw quartets
The file input format must contain 4 groups in the following form:
(Chicken, Human, Loach), (Cow, Carp), (Mouse, Rat, Seal), (Whale, Frog);
Only works in combination with -f q !
-z Specify the file name of a file containing multiple trees e.g. from a bootstrap
that shall be used to draw bipartition values onto a tree provided with "-t",
It can also be used to compute per site log likelihoods in combination with "-f g"
and to read a bunch of trees for a couple of other options ("-f h", "-f m", "-f n").
-#|-N Specify the number of alternative runs on distinct starting trees
In combination with the "-b" option, this will invoke a multiple boostrap analysis
Note that "-N" has been added as an alternative since "-#" sometimes caused problems
with certain MPI job submission systems, since "-#" is often used to start comments.
If you want to use the bootstopping criteria specify "-# autoMR" or "-# autoMRE" or "-# autoMRE_IGN"
for the majority-rule tree based criteria (see -I option) or "-# autoFC" for the frequency-based criterion.
Bootstopping will only work in combination with "-x" or "-b"
DEFAULT: 1 single analysis
--silent Disables printout of warnings related to identical sequences and entirely undetermined sites in the alignment
DEFAULT: Off
--no-seq-check Disables checking the input MSA for identical sequences and entirely undetermined sites.
Enabling this option may save time, in particular for large phylogenomic alignments.
Before using this, make sure to check the alignment using the "-f c" option!
DEFAULT: Off
--no-bfgs Disables automatic usage of BFGS method to optimize GTR rates on unpartitioned DNA datasets
DEFAULT: BFGS on
--asc-corr Allows to specify the type of ascertainment bias correction you wish to use. There are 3
types available:
--asc-corr=lewis: the standard correction by Paul Lewis
--asc-corr=felsenstein: a correction introduced by Joe Felsenstein that allows to explicitely specify
the number of invariable sites (if known) one wants to correct for.
--asc-corr=stamatakis: a correction introduced by myself that allows to explicitely specify
the number of invariable sites for each character (if known) one wants to correct for.
--flag-check When using this option, RAxML will only check if all command line flags specifed are available and then exit
with a message listing all invalid command line flags or with a message stating that all flags are valid.
--auto-prot=ml|bic|aic|aicc When using automatic protein model selection you can chose the criterion for selecting these models.
RAxML will test all available prot subst. models except for LG4M, LG4X and GTR-based models, with and without empirical base frequencies.
You can chose between ML score based selection and the BIC, AIC, and AICc criteria.
DEFAULT: ml
--epa-keep-placements=number specify the number of potential placements you want to keep for each read in the EPA algorithm.
Note that, the actual values printed will also depend on the settings for --epa-prob-threshold=threshold !
DEFAULT: 7
--epa-prob-threshold=threshold specify a percent threshold for including potential placements of a read depending on the
maximum placement weight for this read. If you set this value to 0.01 placements that have a placement weight of 1 per cent of
the maximum placement will still be printed to file if the setting of --epa-keep-placements allows for it
DEFAULT: 0.01
--epa-accumulated-threshold=threshold specify an accumulated likelihood weight threshold for which different placements of read are printed
to file. Placements for a read will be printed until the sum of their placement weights has reached the threshold value.
Note that, this option can neither be used in combination with --epa-prob-threshold nor with --epa-keep-placements!
--JC69 specify that all DNA partitions will evolve under the Jukes-Cantor model, this overrides all other model specifications for DNA partitions.
DEFAULT: Off
--K80 specify that all DNA partitions will evolve under the K80 model, this overrides all other model specifications for DNA partitions.
DEFAULT: Off
--HKY85 specify that all DNA partitions will evolve under the HKY85 model, this overrides all other model specifications for DNA partitions.
DEFAULT: Off
--set-thread-affinity specify that thread-to-core affinity shall be set by RAxML for the hybrid MPI-PThreads version
DEFAULT: Off
--bootstop-perms=number specify the number of permutations to be conducted for the bootstopping/bootstrap convergence test.
The allowed minimum number is 100!
DEFAULT: 100
--quartets-without-replacement specify that quartets are randomly subsampled, but without replacement.
DEFAULT: random sampling with replacements
--print-identical-sequences specify that RAxML shall automatically generate a .reduced alignment with all
undetermined columns removed, but without removing exactly identical sequences
DEFAULT: identical sequences will also be removed in the .reduced file
