I am working on the Pyrosetta tutorial and I am trying to use protein fragments. Howevere there is a problem since the Robetta server keep on failing.
I am submitting this fasta file.
A) Have you tried contacting the Robetta webmaster?
Can you post more details on what error message it gives?
I would guess either your sequence is too short, or it refuses to make fragments for a “test” sequence. The only realistic fragments would be helical anyway.
