[gmx-users] rotacf error
Hi all I want to calculate the order parameter of the NH vector for each amino acids of a protein in a gromacs trajectory for compare with NMR experimental data. I found that it can be calculated using rotacf to calculate the correlation time, when trying to run the program I get an error. In the attached file I show more details about the error andhow I created the index. Could you help me to correct the index for calculate the correlation time and in turn the order parameter S2?

[gmx-users] Recovery simulation error
Hi Gromacs Users. I has been a simulation with gromacs 2016 but my simulation stopped by an energy break. i try to restar in the last checkpoint but this does work and send me this error: Expected output files not present or named differently: cbd211_md.log cbd211_md.xtc cbd211_md.trr cbd211_md.edr Fatal error: File appending requested, but 4 of the 4 output files are not present or are named differently. For safety reasons, GROMACS-2016 and later only allows file appending to be used when all files have the same names as they had in the original run. Checkpointing is merely intended for plain continuation of runs. For safety reasons you must specify all file names (e.g. with -deffnm), and all these files must match the names used in the run prior to checkpointing since we will append to them by default. If the files are not available, you can add the -noappend flag to mdrun and write separate new parts. For mere concatenation of files, you should use the gmx trjcat tool instead. I used this command: gmx mdrun -s cbd211_md.tpr -cpi cbd211_md.cpt -v All the archives ar in the directory Can you help me? Thanks -- *MSc.

[gmx-users] GPU ERROR RUNING A SIMULATION
Hi again every body. I'm tryin running a simulation of a protein in water using Gromacs 2018.3. When i try to minimize the energy in NVT equilibration this send me this error during mdrun: Reading file cbd12_nvt.tpr, VERSION 2018.3 (single precision) Multiple energy groups is not implemented for GPUs, falling back to the CPU. For better performance, run on the GPU without energy groups and then do gmx mdrun -rerun option on the trajectory with an energy group .tpr file. Can you help me please? I don't know what to do in this case and the simulations is very slow... -- *MSc.
