Dear All,

we are experiencing a problem when trying to convert a 2D stack to  
single images:


> e2proc2d.py --unstacking stack.mrcs frame.mrc
76 images, processing 0-75 stepping by 1
1 images

according to the manual this should output a a series of numbered  
single image files, however, it writes only a single 3D image:

> e2iminfo.py frame.mrc
frame.mrc	 1 images in MRC format	2048 x 2048 x 76
representing 0 particles

The input file is reported to be a 2D stack:

> e2iminfo.py stack.mrcs
stack.mrcs	 76 images in MRC format	2048 x 2048
76 total images
representing 0 particles

Versions tested are EMAN 2.21a final and EMAN 2.2 final. Are we doing  
something wrong or is this a bug? Any help appreciated.

Clemens
