Restraint options appear to be ignored in I-TASSER local installation

My local installation of I-TASSER seems to ignore -restraint1/2/3/4 as an input option (it is not listed in the summary when the job is submitted.) Also, the optional arguments list is confusing as to which restraint is appropriate for which option.
-restraint1 links to I-TASSER/option1.html
-restraint2 links to I-TASSER/option4.html
-restraint3 links to I-TASSER/option2.html
-restraint4 links to I-TASSER/option3.htmlrestraint provided, run

Thanks,
Vish
