Dear all,
If i use in ptraj "pucker puck :5.C1' :5.C2' :5.C3' :5.C4' :5.O4' out
pucker.dat" and in Carnal "PUCKER puck NUCLEIC 5" I get completely
different results. My residue should have a C2' endo sugar (meaning
about 144-180 degrees). So, from this point of view the Carnal
calculation seems the correct one while the ptraj seems wrong. Is it
possible to make ptraj give the same results as Carnal (as far as I know
both commands that I used - see above - for ptraj and carnal
calculations use the Altona convention, please correct me if I am wrong.
Thanks a lot for any advice
Vlad
