General discussions (Q&As) / Unknown residue DC
« on: September 13, 2008, 01:19:44 am »
Dear All,

I was trying to run the find_pair program to produce *.inp file. But I am encountering the following error.

unknown residue  DC    1  on chain A [#1]
Check the base and add one more item in file <baselist.dat>


I was executing the command find_pair -t 123D.pdb 123D.inp . It has all the normal base pairs. I have also checked the BASEPAIR.dat file. If I add the following lines in that file, then the program works fine.

 DA     A
 DC     C
 DG     G
 DT     T

These are normal base pairs, So I thought I do not have to modify the file. I have ~500 PDB files and all of them have similar problem.

I want to ask from you whether what I am doing is right or not by modifying the basepair.dat file or perhaps I am missing something.

Eagerly awaiting your reply.

Thanks & regards,
Alok Jain
