Dear users, Its the continuation of the question I asked yesterday, Inorder to reduce the memory usage during g_saltbr calculations i got the trajectory of only protein, and tpr file without water and was able to successfully run it. But unfortunately this again got stopped at 36ns as it had

Its 50ns 25000 frames. the xtc file is 695MB. it has 16GB RAM. So will that be insufficient? I have previously run other analysis which used to take huge memory, for eg. covariance analysis, in a system with much lesser memory even though CPU usage was low the job used to finish. But in this case

Dear Gromacs users, I was running the saltbridge calculations for a dimeric protein simulation using g_saltbr, But its taking very long time, almost four days still its not completed. Could anyone has suggestion regarding this issue? I am using the same system - Intel(R) Core(TM) i7-2600 CPU @

Dear Sir, That is true as the number of the frames increased the memory had almost reached 95% but still it has been in 95% since long and CPU usage drops down to 1.5 -2 % but in many cases i have seen that still it will run (off course slowly) and finish. But this was too long. So any

Dear Sir, I had a problem again during g_saltbr calculation it needs .xtc and .tpr file, I can reduce the .xtc file to have only protein but .tpr file will have water also in it. inorder to generate new tpr file without water using grompp, i need topology file without water .. so do you suggest
