Dear JalView users!

I need to perform large-scale phylogenetic analysis of  big dataset of GPCR
sequences selecting as the input only residues involved in the
ligand-binding site of those receptors (taken from the structural data)
from the input multiple-sequence alignment.  I wounder what method for
phylogenetic trees calculation will be best (neighbourhood joining or
pairs-distance calculations) for my task as well as how to make selection
of the selecting residues properly (previously I've done it by cntrl-left
click on the bottom of the alignment marking corresponded zone by red
colour). On what additional details should I paid my attention during such
calculations in case when I'm dealing with a very big number of sequences?


Thank you for the help,

James
