Rosetta Remodel - Error in core::conformation::Conformation::residue(): The sequence position requested was 0.
#1

Dear caretakers/kind strangers,

I ran into an error that i do not understand when trying to do de-novo modelling of a helix linker using REMODEL. When i leave the blueprint file without any new residues it runs fine. But when i add new residues at the end (C Terminal) the program recognizes it is a C terminal extension, but throws this error.

ERROR: Error in core::conformation::Conformation::residue(): The sequence position requested was 0.  Pose numbering starts at 1.
ERROR:: Exit from: src/core/conformation/Conformation.hh line: 499


This is when i use X for residues.

In this case my blueprint file is structured like this:

1153 M .
1154 E .
0 X L
0 X L

My command is remodel.static.linuxgccrelease -s 5xwp.pdb -remodel:blueprint 5xwp.blp -ex1 -ex2 -num\_trajectory 10.

When i attempt to set specific residues instead of X and use -remodel:use_blueprint_sequence with the above mentioned command i get a segmentation error (core dump).

in that case my blueprint file looks like this:

1153 M .
1154 E .
0 E L
0 K L

and my command is remodel.static.linuxgccrelease -s 5xwp.pdb -remodel:blueprint 5xwp.blp -ex1 -ex2 -num\_trajectory 10 -remodel:use_blueprint_sequence.

relevant output here:

I do not understand what am i doing wrong. I generated the blueprint file per tutorial from the .pl script and i repeat: when i add no residues it runs fine and generates 5 structures. So it is something to do with my new residues that i am adding in the blueprint file. I tried to renumber them continuously like 1154 1155 1156 but then i get a different error in both 1155 1156 and 0 0 numbering :

ERROR: Error in core::conformation::Conformation::residue(): The sequence position requested was greater than the number of residues in the pose.
ERROR:: Exit from: src/core/conformation/Conformation.hh line: 500


So something is wrong with the way i am typing in the new residues. But i do everything per tutorial from documentation: https://www.rosettacommons.org/docs/latest/application_documentation/design/rosettaremodel#algorithm_basic-remodelling-tasks_de-novo-structure_c-terminal-extension

Thanks for assistance.

Hi, Daniloboskovic. I had this problem recently too when I tried to add a linker between two chains. And I solved it by adding 'L' for residues flanking the linker.

Try this:

1153 M .
1154 E L
0 X L
0 X L

I'm new here and hope it helps.
