Dear Peter,

Thank you for your help. I have used the blastp.loc file and renamed it and 
altered it in order to keep the same format as in the previous tool. Also I 
used the same ordering from blastp tool (i.e. 0=value 1=name 2=path). 
Nevertheless when I run my tool I get the error:

Error: Failed to open txt file test_17_Sep_2012 for reading.

I have used chmod 777 for my file but the issue still persists. Can you help me 
please? What could be the problem.

Thank you in advance,
Makis Ladoukakis
