I am very new to modeller so a small query, Please let me know how do I
compare the template sequences using compare script. Do I need to
download individual template files from PDB
Yes, you will need to download template PDB files.
Also, whta should be done in case I have too many template
sequences with same e -value (e.g. 0 e -value) should i download all of
them??
You can if you like - how you choose which template(s) to use for
modeling is up to you.
