Hi Benoit, 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. Tom Benoit Zuber wrote:
Hi,
I was wondering if it is possible to read mrc files where the data type is complex float. I get an error when I try to do that, but maybe there is a way around it (other than converting the data to a non complex type). Typically, this would be useful to read fourier transform volumes.
Thanks, Ben
