Please tell me how to visualize specific grains which have particular grain IDs

Hello,

I want to visualize specific grains which have particular grain IDs.
I tried the command below, but the correct grains don't visualize:

neper -V n50-id1.tess,n50-id1.msh -showcell "file(grain-ids.txt)" -print img

The actual number of grains I want to visualize is about 1000.
Please tell me how to visualize specific grains which have particular grain IDs
The format of "grain-ids.txt" is as follows:

2
3
5
6

The file must contain 1000 entries (one for each grain) equal to 0 (to hide a grain) or 1 (to show a grain). See -showcell.

Thank you! I was able to solve the problem using that method.
