How can I "mimic" Quark using I-TASSER standalone?

Hi,

I made a post the other week about trying to get structures of hundreds of peptides that have minimal homology to known proteins: http://zhanglab.ccmb.med.umich.edu/bbs/?q=node/4205

I can run the I-TASSER standalone software with the default settings, but it's a bit slow. Could I speed it up by leaving out some of the homology modeling calculations? Like by changing "-homoflags" to "benchmark" or adjusting the "-ntemp" number?

Thanks
