usage: prog [options] Tiltvalidation using Richard Henderson's technique. To use a stack of untilted and tiltimages whose set relationship is one-to-one is required along with a volume to validate. This can be generated using e2RCTboxer.py. After running this program two bits of data are products. A contour plot similar to Figure 5 in the Henderson paper(see below), and a list of titlangles and tiltaxes between particle paris, which can be used to makes plot similar to Figure 6 in Hendersons paper. The contour plot is stored as contour.hdf and the tiltpairs data is stored as bdb:perparticletilts.
