Rigid body from multiple chains
by Komjati Kornel 26 Feb '18

26 Feb '18

Hi, I would like to model a protein with multiple chains (A,B,C,D) as an entire rigid body. Unfortunately I cannot find a way to do this, it seems like that a rigid body can only contain one protein chain. Is there any method to create my desired model? Thanks in advance, Kornel

running imp with DNA sequence
by מירב בריטברד 05 Feb '18

Hi, Part of the structure that I am trying to find is a DNA sequence and not a protein. I have pdb with the DNA part, and I create a fasta file (both attached) but when I am running IMP, it's write this warning: "BuildSystem.add_state: -------- domain 0 of molecule DNA_1 represented by pdb file /cs/labs/dina/meravb/CENP_new_cross_links_and_PDB_renumbered/pdb_files/Nuc_numbering_fixed_in_map.pdb WARNING: Replacing sequence residue 1 "THR" with PDB type "DC" WARNING: Replacing sequence residue 2 "GLY" with PDB type "DT" WARNING: Replacing sequence residue 3 "CYS" with PDB type "DG" WARNING: Replacing sequence residue 4 "ALA" with PDB type "DC" WARNING: Replacing sequence residue 5 "GLY" with PDB type "DA" WARNING: Replacing sequence residue 6 "ALA" with PDB type "DG" WARNING: Replacing sequence residue 7 "THR" with PDB type "DA" WARNING: Replacing sequence residue 8 "THR" with PDB type "DT" WARNING: Replacing sequence residue 9 "CYS" with PDB type "DT"....." How can I run in imp in a way that will recognize the DNA? Thanks, Merav
