PennCNV run error (Can't exec detect_cnv.pl) Linux

[gaiusjaugustus]

I am trying to get PennCNV working on my computing server. Here's what I've done, per this document: http://penncnv.openbioinformatics.or...guide/install/

• Downloaded + decompressed
• loaded perl (5.14.2) & R/2.15.2 modules
• went to kext folder and used make
• went to penncnv folder and typed "perl ./detect_cnv.pl". The usage information appears
• added to my export PATH = statement in my bashrc file, "$HOME/opt/penncnv" where the files are located

I then went to the example folder to try to run those, using this document as a guide: http://penncnv.openbioinformatics.or...guide/startup/

• Ran "perl runex.pl", got usage information
• Ran "perl runex.pl 1", and got "Can't exec detect_cnv.pl: (null) at example/runex.pl line 81"
• Ran "perl runex.pl -path_detect_cnv ../detect_cnv.pl", same error occurs.
• Also tried going up to the main penncnv folder and using "perl example/runex.pl 1 -path_detect_cnv detect_cnv.pl", but get the same error.

Any suggestions/advice?

Thanks in advance,

Gaius
