I am new user to the modeler, I have started with the basic tutorial, I have difficulty with plotting the dope scores with GNU plot,
when I plot the two dat files '1bdma_dope.dat','TVLDH_dope.dat'(from the tutorials folder) I get the graph plotted(Dope score vs Residue Index), but the two graphs are not aligned, as shown in the tutorial html file. how to align the graphs. hope someone could help me with this silly doubt.

Modeller does not do anything special for transmembrane proteins; it
simply extracts restraints from the template structures. Note, however, that Modeller's internal database of protein alignments, used to derive statistics, include no transmembrane proteins, so it may not behave as
well as for globular systems.
Charlotte, thank you for your reply. However, I have included the number of nucleic acid residues in the description line of the structure and sequence.
Actually, I have tried to model both the case of only nucleic acids, as
well as the case of protein+nucleic acids.
(1) Modelling only nucleic acids - results in the following error: rdpdb___303E> No atoms were read from the specified input PDB file, since the starting residue number and/or chain id in MODEL_SEGMENT (or the
alignment file header) was not found; requested starting position: FIRST: @
(2) Modelling protein+nucleic acid - results in the following error: csrrng__299E> Atom index is out of bounds: 7621 7620
nselat__596E> Atom index is out of range (iatm,natm): 7621 7620
I have a question: Will Modeller allow for modelling only nucleic acids (without protein), or does it need to have the nucleic acids modelled along with protein?
I am still unable to model nucleic acids (either by itself or with protein) using Modeller and would appreciate any suggestions on corrections/changes to make.
With thanks and regards Nisha

Does anyone out there know if it is possible to find a description of the DOPE score? I have been searching the manual, the MODELLER web-site and the www...
Thanks in advance Leyla
