[Chimera-users] reading complex-float mrc files

Chimera cannot read volume data with complex values. It would be
nice, but it would require special case handling in a lot of Chimera
code: histogram display, contour levels, coloring by value, all could
use the magnitude of the complex data values. But that could all be
done by starting with a different volume data set that holds the
magnitudes of the complex values. As you point out using the complex
values could have use with Fourier analysis and there might even be
specific visualization methods like looking at the complex phase. I'll
put this on our feature request list but I think it is unlikely to ever
be done given the many more widely useful enhancements already requested.
