I have to use a template, whose PDB ID is 1APS. It is *NMR Model *with
four models.
I have to use only *first model of this NMR* structure.
This is fine - Modeller will only read the first model from NMR structures.
For this template, I have *50 Query sequences* in 50 separate ".fasta
files" in PIR FORMAT.
Are they FASTA files or PIR files? You need PIR files for modeling.
*Description of PIR Format of Query sequences:*
*First line: *>1APS_1; Mutant_Y15M
*Second Line:* I think this line is optional - I HAVE OMITTED THIS LINE.
My second line is PROTEIN SEQUENCE in Capital letters ending with " * ".
What you describe is not a valid PIR file. You can find a description of
the file format at
