Thank you for the great code. I am trying to use it to diffusivity of O (in water molecules). Following your approach, I dump the trajectory as follows:

dump 2 all custom 2000 dump_npt_step04.lammpstrj id mol type x y z vx vy vz

See the data file here (https://file.io/u989fgFsemUj). I used moltemplate to create the lammp input files. How do I go about specifying the --mol and --nummol for my system. Thanks.

For a water system with 6420 water molecules, I tried :

python PyLAT.py -T 300 --nummol 2140 --mol OW --nummol 4280 --mol HW -d -v 2 log.lammps npt_stp04.data dump_npt_step04.lammpstrj

and got the following error:

beginning COM calculation
COM calculation 100.00% complete
beginning MSD calculation
unwrap complete

  File "<__array_function__ internals>", line 5, in dot
ValueError: shapes (2140,) and (6420,) not aligned: 2140 (dim 0) != 6420 (dim 0)

Please advice.
