ADL: Using ADCP with custom peptide?

[Gustavo Seabra]

Hi,

I wonder if it is possible to use ADCP with a custom peptide, maybe by
giving the pdb file of the peptide, instead of having ADCP build the peptide
itself from sequence. 

I'm trying to run it as:

       $ adcp --target target.trg \
                  --input ligand.pdb \
                  --numSteps 5000000 \
                  --nbRuns 100 \
                  --maxCores 8 \
                  --overwriteFiles \
                  --natContacts 0.8 \
                  -o docked

But I keep getting errors in the log file, for example:
$ cat docked.out
found external potential parameters 1
found external potential parameters 4
setting constrained list file constrains
found external2 potential parameters 4
setting cyclic peptide constrains

I wonder if anyone here would have an idea on what could I be doing wrong.

Thanks!
