I am trying to do a de novo protein folding from a protein sequence with repeating Gly and Arg only.
So the sequence looks like GRGRGRGRGR..... I put the sequence onto Robetta Fragment Server and it gave me this error message:

sam target99 failed!
This might be a dumb question but I was wondering if there are some restrictions on the usage of de novo protein folding in Rosetta when the sequence is repeating...?
Thanks for your help!
