Have you tried ACORN starting from a random atom?

Subject: [ccp4bb] Molecular Replacement of a small peptide
I am trying to do molecular replacement on a small peptide (less than 40 AA)
and have not had any success using phaser. Are there any tricks or better
programs for really small peptides?
The data is great 1.1 A, ~35% solvent, and two molecules in the ASU. I have
tried all the standard stuff, changing resolution cut off etc. I may move to
sulfur phasing at this resolution but I would like to get the MR to work.
