usage: prog [options] 
	This is a program to compute the resolution of a n averaged subtomogram. Right now it is very simple simple divide the aligned
	subtomos into even/odd classes, average and then compute the FSC. In the future this program will be extended to compute 
	resolution of an averged subtomo vs a reference and hopefuly of a single sub/tomogram.

Option Type Description
--version None show program's version number and exit
--averager str The averager used to generate the averages. Default is 'mean'.
--sym str The recon symmetry
--mask str The mask to apply before FSC calculation
--ppid int Set the PID of the parent process, used for cross platform PPID
