Helping the module find your executable¶

You will need to help MSAProbs to find the 'msaprobs' executable. This can be done in (at least) three ways:

  1. Make sure the msaprobs executable is in your path (i.e. 
     'which msaprobs' returns a valid program)
  2. define an environmental variable MSAPROBSDIR which points to a 
     directory containing the 'msaprobs' app:
   In bash 
        export MSAPROBSDIR=/home/progs/msaprobs   or
   In csh/tcsh
        setenv MSAPROBSDIR /home/progs/msaprobs
  3. include a definition of an environmental variable MSAPROBSDIR 
      in every script that will
     BEGIN {$ENV{MSAPROBSDIR} = '/home/progs/msaprobs'; }
     use Bio::Tools::Run::Alignment::MSAProbs;

Mailing Lists¶

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support¶

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
