Specifying Template Name errors

Hello,

I am trying to fold using I-TASSER2.0 and specifying the template name in the PDB. I am getting the following errors in err.txt, and hope someone could help me resolve them. I specified the restraint as -restraint3 3HC7:A
The errors follow:

/bin/rm: cannot remove `/tmp/chiraagk/mkres_seq/templatedir': Is a directory
