Dear Teemu Murtola
I study interaction of protein-dna in water. I want to obtain number of
water molecule which are simultaneously closer than 3 A° from protein and
DNA.
my selection.dat file is as follows:
waterO = group SOL and name OW;
heavy1 = group Protein and group "Protein-H";
heavy2 = group DNA and group "Protein-H";
inter = waterO and within 0.3 of heavy1 and within 0.3 of heavy2;
inter;
when I use g-select -f .xtc -s .tpr -n .ndx -sf ,
selection parser: syntax error
heavy1 = group Protein and group "Protein-H"'
-------------------------------------------------------
Program g_select, VERSION 4.5.1
Source code file: trajana.c, line: 1310
Input error or input inconsistency:
selection(s) could not be parsed
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
Am I doing it incorrect ? Is there problem in my .ndx file?
Is this error a bug in gromacs 4.5.1?
