Hello,
When I use read_data to read a text file, I always get one of the two error message:
“Did not assign all atoms correctly”, “Unexpected end of data file”
I have searched the mailing list. It looks like there are two cases which might cause this problem: too small box, no blank line below the section keyword. After I checked my data file, I didn’t find these two mistakes. Could anyone tell me why I got this error message? The following is my data file ( for a 2D system, atom_style is hybrid charge bond):
