Chimera keeps volume data in memory using the same numeric value
types that are present in the file, for example, 32-bit float, 16-bit
integer, 8-bit integer.
Volume data is copied only when necessary -- for instance, using the
Gaussian Filter tool creates a floating point copy of the data since
Gaussian convolution of integer data produces a floating point result.

> map is in 2 byte integers), making the mode of the MRC file irrelevant
> to chimera's performance?
