[gmx-users] g_sdf : error

[Nilesh Dhumal]

Hello,
I am trying to run g_sdf for sovlation for glucose in ionic liquids.
I am trying to find distribution of anion around glucose.


g_sdf -f 3.trr -n glu-emi-cl-128-no.ndx -s -mode 1 3.tpr -o sdf.plt -r

First three group I selected from the same residue (Glucose). Forth grouup
I selected from as anion (Anion residue ). I am geting following error.

Fatal error:
For single particle SDF, all reference groupsmust have the same size.

Thanks

Nilesh
