subtom_parallel_sums_bfactor
Subsets version of parallel sums for finding B-factor.

'all_motl_fn_prefix', all_motl_fn_prefix ('combinedmotl/allmotl'),
'ref_fn_prefix', ref_fn_prefix ('ref/ref'),
'ptcl_fn_prefix', ptcl_fn_prefix ('subtomograms/subtomo'),
'weight_fn_prefix', weight_fn_prefix ('otherinputs/ampspec'),
'weight_sum_fn_prefix, weight_sum_fn_prefix ('otherinputs/wei'),

'num_avg_batch', num_avg_batch (1),
'process_idx', process_idx (1))
Aligns a subset of particles using the rotations and shifts in
all_motl_fn_prefix _#.em where # corresponds to iteration in
num_avg_batch chunks to make a raw particle sum ref_fn_prefix _#_###.em
where # corresponds to iteration and ### corresponds to process_idx.
Fourier weight volumes with name prefix weight_fn_prefix will also be
aligned and summed to make a weight sum weight_sum_fn_prefix _#_###.em.
tomo_row describes which row of the motl file is used to determine the
correct tomogram fourier weight file. iclass describes which class outside
of one is included in the averaging.
The difference between this function and the other version of subtom_parallel_sums is that this function creates a number of subsets of the particle and weight sum subsets, so that smaller and smaller populations of data are summed, and these subsets can then be used to estimate the B-Factor of the structure.
