[Chimera-users] Monitoring hbonds in chimera

Dear Dr. Gandhi,
The second findhbond command will erase the previous H-bonds (from the first findhbond command) unless you use the "retainCurrent true" option in the second findhbond command.
Another problem I can see is that there should be a space between "selRestrict" and "both". Other possible reasons for no Hbond to be shown are:
(a) the atoms do not meet the criteria (for example, they are too far apart)
(b) your select command didn't select the atoms (for example, if their names didn't match what was in your command)
You can the commands by entering them into the command line before putting them into a script. If the residues are already displayed, you do not need "reveal true"
I hope this helps,
