identical with the tutorial but with error output message?make sure all the input file is correct especially the trajectory,which seems have some mistake from the error message.

主题: [AMBER] H-bond analysis in ptraj
 
Hi all,
I am doing H-bond analysis of pr with solvent in order to see the solvent effect on pr . But when I did ,it just ran a short time , showing that :
                                     checking coordinates: equil1-6.binpos
                                    Error in safe-malloc: Error in alloc of - 1216928392 bytes
The analysis progress is according a example in the amber tutorials .
The following is the ptraj script:
analyse_hbond.ptraj
trajin equil1-6.binpos

#-- series hbt is just a placeholder to ensure we get the full analysis. If you don't

What is wrong with that? My computer is 3.0GHz and 1G memory. Or My analysis meaning to is unreasonable? Any help is appreciated .
sincerly,
Lisa
