Increase maximum filename size about pftools3 HOT 10 CLOSED

Hi
pfscanV3 (pfscan rewritten in C++ with heuristic improvements) should not have such issue.
Could you use that one or the old pfscan is mandatory for you?

Hi,

Thanks for your suggestion. In fact, most of the time, we don't use use pfscan directly but we use interproscan which in turns use ps_scan.pl which in turns use pfscan (hence we also reported #9).

Is there a way to force interproscan to use v3 ?

from pftools3.

Development of pftools V3 started years ago following a request of interproscan to speed up queries on Prosite.
So interproscan should have a way to switch to pftools v3 somewhere

AFAICS, pftoolsV3 is not in the binaries provided by interproscan so I think that this is not possible right now. I have asked them.

@duboism thanks for this update. We had tested pfsearchV3 in InterProScan probably at v3.0 when it was at ftp://ftp.lausanne.isb-sib.ch/pub/software/unix/pftools/pftoolsV3, but we found it wasn't stable enough to include in InterProScan for public use. We had identified errors which were fixed and the fixed version sent to us but the files and the documentation at ftp://ftp.lausanne.isb-sib.ch/pub/software/unix/pftools/pftoolsV3 were not updated.

We will now test the new version

Hi @duboism
Patches have been applied to increase the filename size for pftools v2. The new size follows today usage on Linux.

Could you let us know if it works for you? This is in the master branch.

Sorry, I missed the notification. I will be happy to help but I don't know how to use pfscan. Can you provide a simple example ? I will then test with increasing file name length.

from pftools3.

Here are two examples coming from the test suite (files are in the tests/examples/ folder)

pfscan -s GTPA_HUMAN.dat prosite13.prf
pfscan -by -C 2 CVPBR322.embl ecp.prf

from pftools3.

I tested pfscan with longer and longer filename. For the tag v3.2.5 (before #12), pfscan starts to fail if the filename is longer than 512: one can clearly see that filename truncated to 512 in pfscan and it returns 1. For the current master, the shell will start to fail when the filename is longer that 4096.

So I can confirm that it works now. 👍

Great!
Thank you for testing
