Hello all,

https://pubs.acs.org/doi/full/10.1021/acs.jcim.5b00674
https://pubs.acs.org/doi/suppl/10.1021/acs.jcim.5b00674/suppl_file/ci5b00674_si_001.pdf

I guess my error coming from this part (I am not so sure)

.<TRIPOS>MOLECULE
LIG
   52 52 1 0 0
SMALL
bcc


.<TRIPOS>ATOM
      1 N 144.1030 198.5620 176.9400 n3 0 LIG
 -0.701600
      2 N1 141.3350 198.1970 175.9020 n3 0 LIG
 -0.711600
      3 N2 140.5480 196.7460 178.3670 n3 0 LIG
 -0.774600
      4 N3 143.3260 197.1060 179.4180 n3 0 LIG
 -0.711600
      5 O 144.9280 195.9750 177.2280 o 0 LIG
 -0.871800
      6 O1 143.2880 196.5480 174.8890 o 0 LIG
 -0.869550
      7 O2 141.0920 195.2010 176.1420 o 0 LIG
 -0.622100
.......................................................................................................................

When I change the name of LIG as a RES -everything is fine. (I saw the RES
name in the second example in the zip file (
https://pubs.acs.org/doi/full/10.1021/acs.jcim.5b00674)

 but I didn't clearly understand the "naa_mol2files" )

So my question
Is RES a general name for ligand part or How can I write valid general name
for the ligand part?

I hope I am clear.

I looking forward to your answers.

Cheers

Işılay
