Print molecule info for selected atoms.
molinfo [parm <name> | parmindex <#> | <#>] [<mask>]
Print molecule information for atoms in <mask> for selected topology (first loaded topology by default) with format:
#Mol Natom #Res Name [SOLVENT]
where #Mol is the molecule number, Natom is the number of atoms in the molecule, and #Res and Name are the residue number and residue name of the first residue in the molecule respectively. SOLVENT will be printed if the molecule is currently considered a solvent molecule.
