[gmx-users] Space between the columns in the topology file of Gromacs

[lan hoa Trinh]

Dear Gromacs society,
I wonder if there is the default for the space between the columns in the
topology file, for example:
[ bonds ]
;ai     aj      func    r0(nm)  Kb
        1        2     1 3.805916447e-01 2.000000000e+04
        2        3     1 3.788218579e-01 2.000000000e+04
        3        4     1 3.790369375e-01 2.000000000e+04

Should it be fixed that ai, aj  at the fix positions, i.e. 8 spaces of tab
size for example?
I am looking forward to hearing from you.
Best regards,
