Dear Amber users
I I want to run a MD of a kinase in complex with ATP.
To build ATP parameters I used files .frcmod and .prep found on
http://www.pharmacy.manchester.ac.uk/bryce/amber/ and I loaded them in tleap.
I used the following script:
source leaprc.ff99SB
loadamberparams ATPphos.frcmod
loadamberprpe ATP.prep
ATP = loadpdb ATP.pdb
saveoff ATP ATP.lib
saveamberparm ATP ATP.prmtop ATP.inpcrd
quit
I got the following error:
Loading parameters: ./ATPphos.frcmod
Reading force field modification type file (frcmod)
Reading title:
# Modifications to the AMBER94 force field for polyphosphates
ERROR: syntax error
Loading PDB file: ./ATP.pdb
Unknown residue: ATP number: 0 type: Terminal/last
..relaxing end constraints to try for a dbase match
-no luck

Failed to generate parameters

It looked like tleap did not recognize the ATP atom types.
I changed all atom names in the pdb file of ATP according to the atom types used in the file .prep and I got the same error.
Any suggestion to understand and solve that problem?
Thank you
Valentina
