[gmx-users] g_select help

[rajat desikan]

Hi All,
I have a dopc+50% cholesterol bilayer. I want to selectively choose the
upper and lower leaflets. I used g_select the following way
g_select -s DOPC_0.5chl.gro -select 'resname DOPC and resname Cholesterol
and z>6' (6 is the COM of my box)

I am getting the following error.
Possible bug:
one of the values for comparison missing

g_select -s DOPC_0.5chl.gro -select 'resname DOPC and resname Cholesterol'
works perfectly fine. What is the problem?

Thank you.
