Hi Bipin,

The file residuetypes.dat is quite different from aminoacids.dat. You
can paste the following into that file (first line is number of
entries, followed by so many residue names):

49
ABU
ACE	
AIB
ALA
ARG
ARGN
ASN
ASN1
ASP
ASP1
ASPH
CYS
CYS1
CYS2
CYSH
DALA
GLN
GLU
GLUH
GLY
HIS
HIS1
HISA
HISB
HISH
HYP
ILE
LEU
LYS
LYSH
MELEU
MET
MEVAL
NAC
NH2
PHE
PHEH
PHEU
PHL
PRO
SER
THR
TRP
TRPH
TRPU
TYR
TYRH
TYRU
VAL


Groetjes,

Tsjerk
