I'm working on a server where users should be able to run protein sequences against a database, and it uses an executable called blastall. The server generates an executable which it should then run using batch. However, it doesn't appear to be running. Here is an example of an executable is generates (cmd.sh):
#!/usr/bin/env sh
cd /var/www/dbCAN
php -q /var/www/dbCAN/tools/blast.php -e -w /var/www/dbCAN/data/blast/20121019135548
Where the crazy number at the end of that is an auto-generated job ID based on when the job was submitted. There are 2 issues, and I'm trying to solve one at a time. The first issue is that when manually executed (by me simply running ./cmd.sh), I get the following errors:
sh: 1: /var/www/dbCAN/tools/blast/bin/blastall: not found
sh: 1: /var/www/dbCAN/tools/blast/bin/blastall: not found
sh: 1: -t: not found
But this doesn't really make sense to me, as the directory specified does in fact contain blastall. It has full rwx permissions and every directory along the way has appropriate permissions.
The blast.php file in tools looks like this:
try {
do_blast($opts["w"]);
$info['status'] = 'done';
$fp = fopen("$opts['w']/info.yaml","w")
fwrite($fp, Sypc::YAMLDump($info)); fclose($fp);
}
With of course variable declarations above it, and the do_blast function looks like this (again with variables declared above it and a cd so the directories work out):
function do_blast($workdir)
{
system("/var/www/dbCAN/tools/blast/bin/blastall -d data/blast/all.seq.fa -m 9 -p blastp -i $workdir/input.faa -o $workdir/output.txt")
system("/var/www/dbCAN/tools/blast/bin/blastall -d data/blast/all.seq.fa -p blastp -i $workdir/input.faa -o $workdir/output2.txt")
}
Any idea what may be causing this issue? I thought it may be because I'm running it and it was created by apache, but rwx is allowed for all users. I can include more information if needed, but I chose not to at this point because the original person who wrote the PHP split up everything into tons of little files, so it's difficult to pinpoint where the problem is exactly. Any ideas (if not complete solutions) are very appreciated.
EDIT: Solution found. As it turns out, the blastall executable had been compiled on a different linux system. Switched to a different executable and it ran flawlessly.
The solution was to recompile the blastall executable. It had been compiled for Redhat and I am using Ubuntu. Unfortunately I assumed the executable I was given was for my system, not the previous one.
