Dear Amber users,
I got the following error when tried to run "tleap" during the simulation of DNA complexed with 2,5' bis(4-guanyl)furan. Please help me solve this!!!!!
The error is as follows
Loading PDB file: /home/student/remya/227D/complex_setup/227d_dna_BGF.pdb
Unknown residue: BGF number: 24 type: Terminal/last
..relaxing end constraints to try for a dbase match
