Import 3D volume total size of new array must be unchanged

I have a hard time importing my .mrc file in 3D volume.

I use chimera volume viewer to save it for my mask.
Does anyone have this issue before?

Hi @wanting_wei,

This error usually means the information in the header of the MRC file doesn’t match the information that is actually on disk. Your volume file may be corrupted, or Chimera may have modified the header incorrectly. If possible, can you open up the MRC file header to inspect it and double check that the dimensions (nx, ny, nz) match what you expect the volume to be?
