Hi, I am trying to calculate the angle between P and N vector of my lipid (popc+popg) with regards to the z axis to see how the protein is affecting the membrane. I am using this command, but it does not working gmx select -f *.xtc -s *.tpr -select POPG & name P* N* within 1.0 of Protein -oi number.dat but the problem is, when the command is running only gmx select -f *.xtc -s *.tpr -select POPG this command. Can anyone please guide me what i am doing wrong. Thanking you Shahee -- Gromacs Users mailing list
