Hi Silvana and everybody,
my personal opinion is that Modeller is a bit intimidating for making first
experiences with homology modelling. You could use the Expasy Swiss model
server - you don't have to install a thing to play around a bit, and whenever
you start wiorking on a project and know more about modelling, it may be time
to get Modeller up and running. best wishes,
a happy Modeller user (margot)
