usage: prog [options] 
	This program stacks DDD frames saved as independent files but collected as part of a tomographic tiltseries, provided that the tilt angle
	information is in the filename between '[' and ']'; e.g., "afsdas_img1234_[-60.0].mrc", "afsdasd_img1235_[-60.0].mrc", "asdfasd_img1236_[-60.0].mrc", 
	... "afsdasfad_imgN_[-58.0].mrc", etc.

Option Type Description
--version None show program's version number and exit
--apix float default=0.0 (not used). Reset the apix on the header of each image to this value.
--extension str default=.mrc. Valid choices are .mrcs, .hdf, .tiff
--inputstring str default=.mrc. String common to all images to be processed. E.g., with '.mrc' as the default, all files in the directory ending in '.mrc' (or containing this as part of the filename) will be analyzed.
--nframes int default=0 (not used). Number of expected frames per tilt angle, used to check whether errors occur in the stacking of images.
--outputstem str default=stack. Output filename stem/root to write stacked frames out to; e.g., "stack_01", "stack_02", "stack_03", etc. Explicitly choose an extension/format by supplying --extension; e.g., --extension=.hdf, and the output will be 'stack_01_angle+02.hdf','stack_02_angle+00.hdf','stack_03_angle-02.hdf', etc, etc.
--ppid int Set the PID of the parent process, used for cross platform PPID
--twodstack None default=False (not used). Produces a stack of 2D images (Z number of images of X,Y size under the same "virutal stack" file name). By default, the output stack will be a 3D stack (a single image of size X,Y,Z, where Z is equal to the number of stacked frames).
--verbose, -v int verbose level [0-9], higher number means higher level of verboseness.
