$ RepeatModeler --help No database indicated NAME RepeatModeler - Model repetitive DNA SYNOPSIS RepeatModeler [-options] -database <XDF Database> DESCRIPTION The options are: -h(elp) Detailed help -database The prefix name of a XDF formatted sequence database containing the genomic sequence to use when building repeat models. The database may be created with the WUBlast "xdformat" utility or with the RepeatModeler wrapper script "BuildXDFDatabase". -engine <abblast|wublast|ncbi> The name of the search engine we are using. I.e abblast/wublast or ncbi (rmblast version). -pa # Specify the number of shared-memory processors available to this program. RepeatModeler will use the processors to run BLAST searches in parallel. i.e on a machine with 10 cores one might use 1 core for the script and 9 cores for the BLAST searches by running with "-pa 9". -recoverDir <Previous Output Directory> If a run fails in the middle of processing, it may be possible recover some results and continue where the previous run left off. Simply supply the output directory where the results of the failed run were saved and the program will attempt to recover and continue the run. -srand # Optionally set the seed of the random number generator to a known value before the batches are randomly selected ( using Fisher Yates Shuffling ). This is only useful if you need to reproduce the sample choice between runs. This should be an integer number.

Installation notes
RepeatModeler has a number of dependencies. How these are installed are detailed below:
nseg
nseg and nmerge (included in nseg) are quite old programs coded in C by NCBI. These were installed on all machines in /usr/local/bin
RECON
The same is done with RECON, which consists of the following executables:
- imagespread
- eledef
- eleredef
- edgeredef
- famdef
So all these are now available in /usr/local/bin in the nodes as well.
RepeatScout
As this also only includes two C-coded executables with quite good names, it is easy enough to install it locally on all the nodes:
- RepeatScout
- build_lmer_table
and also the following perl scripts (using the unusual *.prl extension) must be also be installed:
- filter-stage-1.prl
- filter-stage-2.prl
- merge-lmer-tables.prl
- compare-out-to-gff.prl
RepeatModeler itself
This is quite similar to RepeatMasker, although there is an opportunity to manually edit RepModelConfig.pm.tmp which is more accurate and convenient than the automatic configure script. Predictably, it will only be active when the tmp extension is hived off.
