[gmx-users] Warning while loading .gro generated from .pdb with pdb2gmx

[Pacho Ramos]

Looks like I am unable to attach the offending pdb file because mailing
list imposes a size limit of 50 Kb for the whole message (including
attachments) and the file is around 1 MB, what way do you prefer for
providing the file?

Thanks for the info
