[Chimera-users] About volume viewer in chimera 1.6.1

[Elaine Meng]

Hi Yuhong,
Those numbers are the grid dimensions of the map file: how many grid points (density values) it contains in the X, Y, and Z directions.  For example, in your figure:

fishmonomer4.mrc has 88 grid points along X, 66 along Y, 94 along Z (total number of values 88 x 66 x 94)

1akeA_10A.mrc has 22 values along X, 22 along Y, 22 along Z (total number of values 22 x 22 x 22)

I hope this helps,
Elaine

Here I attach a picture and inside the picture there are two places I've point out with arrows which represent two different map files in mrc fornat.
