cd-hit-para.pl - divide a big clustering job into pieces to run cd-hit or cd-hit-est jobs
SYNOPSIS
cd-hit-para.pl options
DESCRIPTION
This script divide a big clustering job into pieces and submit jobs to remote computers over a network to make it parallel. After
all the jobs finished, the script merge the clustering results as if you just run a single cd-hit or cd-hit-est.
You can also use it to divide big jobs on a single computer if your computer does not have enough RAM (with -L option).
Requirements:
1 When run this script over a network, the directory where you
run the scripts and the input files must be available on all the remote hosts with identical path.
2 If you choose "ssh" to submit jobs, you have to have
passwordless ssh to any remote host, see ssh manual to know how to set up passwordless ssh.
3 I suggest to use queuing system instead of ssh,
I currently support PBS and SGE
4 cd-hit cd-hit-2d cd-hit-est cd-hit-est-2d
cd-hit-div cd-hit-div.pl must be in same directory where this script is in.
Options
-i input filename in fasta format, required
-o output filename, required
--P program, "cd-hit" or "cd-hit-est", default "cd-hit"
--B filename of list of hosts,
requred unless -Q or -L option is supplied
--L number of cpus on local computer, default 0
when you are not running it over a cluster, you can use this option to divide a big clustering jobs into small pieces, I suggest you
just use "--L 1" unless you have enough RAM for each cpu
--S Number of segments to split input DB into, default 64
--Q number of jobs to submit to queue queuing system, default 0
by default, the program use ssh mode to submit remote jobs
--T type of queuing system, "PBS", "SGE" are supported, default PBS
--R restart file, used after a crash of run
-h print this help
More cd-hit/cd-hit-est options can be speicified in command line
