[modeller_usage] sequence file produced is different from the one shown in the tutorial



Hi everyone,

I am working on the example given in the modeller tutorial http://salilab.org/modeller/wiki/Missing%20residues. I used the exact same script to generate the sequence file. Instead of the given pdb1qg8.ent , I used the 1qg8.pdb downloaded from www.rcsb.org.  When I ran the script it resulted in the following sequence file (1qg8.seq)


>P1;1qg8

In the field 5, it says +238 whereas in the tutorial, in the resulting 1qg8.seq file it shows 256. Have I done any mistake? Would the above sequence file work just as fine as the one shown in the tutorial?

Thank you
