Dear sir/madam,
 
 
                     I have a doubt in plotting the graph for calculating the  DOPE Score using GNUPLOT. In GNUPLOT using the command 'plot "TvLDH.profile" using 1:42 with lines'. (From the Tutorial ) Only a single graph is shown but in the tutorial 2 lines of 2 profiles are shown.(TVLDH.profile showing red & green )
My question is how dow we compare the DOPE Score of 2 or more profiles using GNU plot. Please give me a posetive reply

You should follow the advice in the error message, and check your
alignment file header. Your header tells Modeller to read residues 11:A
through 438:B from your PDB file, so it's not going to read the HETATMs,
which come after 438:B. Fix your alignment header.

BTW, your PDB file contains 4 HETAMs (two SO4 and two PLP) but your
alignment sequence contains only two.

hi all,
i got success to build a 2chain model with two ligand.I am sincerely thankful to Ben Webb,modeller care taker for all this thing .but now I have another question :P...last portion of my final PDB look like this
ATOM   6730  C   ASN B 852       5.358  41.203   4.902  1.00 44.07       2SG6732

HETATM 6738  S   SO4 C 854       1.214  44.486  35.947  0.40 11.34       3SG6741

here you can see that modeller take HEATATMs as chain C.then my question is whether ir hamper the model or not.will it acceptable???
regards
sanjay
