Bugzilla Bug 102258

# The gentoo ebuild sci-biology/trnascan-se-1.23 is broken
# 1) missing soft links
# 2) wrong hard-coded path in the main perl script
#

###################
# fix soft links:

ln -s /usr/share/trnascan-se/TPCsignal /usr/bin/TPCsignal
ln -s /usr/share/trnascan-se/Dsignal /usr/bin/Dsignal

###################
# fix paths in file tRNAscan-SE (main perl sript of tRNA-scan-SE)

rhone bin # diff tRNAscan-SE.orig tRNAscan-SE

Reproducible: Always
Steps to Reproduce:
1. emerge sci-biology/trnascan-se-1.23
2. run a test analysis e.g. "./tRNAscan-SE.orig /tmp/test.fasta" , where
test.fasta is a dna sequence file in FASTA format


Actual Results:  
FATAL: Unable to open TRNA2-euk.cm covariance model file


Expected Results:  
write results to standard output

Thanks for reporting, Thierry. I fixed the problem. (Symlinks were not   
necessary once the hard-coded paths were corrected; all files were found   
without problem and I successfully tested some random DNA sequence for  
tRNA presence.)   
   
Merci, et bonne chance dans tes travaux.
