I-TASSER for Protein Sequences Longer than 1500 Resides

Hello,

I am trying to run a locally running I-TASSER5.1 package for longer protein sequences (>1500 residues). I tried to modify "runI-TASSER.pl" program to be able to run for long sequences. In line 477 of " runI-TASSER.pl", I changed the upper range of the sequence to 2000. Next, I ran the program with this change and got error message "bzip2: Can't open input file rep*.tra: No such file or directory.". This indicates that the trajectory files are not being created.

Could you please help me to run the I-TASSER5.1 program for sequences longer than 1500 residues.

I appreciate your help in this regards.

Sincerely,
Avdesh Mishra
