optional cell cluster factor
optionall internal priming info, as produced by find.ip.sites() function
minimal total (dataset-wide) number of molecules for an exon to be considered expressed
number of cores to use
use either h5 or hdf5r to read the input hdf5 file
a list containing gene structural information data structure ($gene.df, with el,il, nex,nipconc,nipdisc columns corresponding to the log10 exonic length, intronic length, number of exons, numebr of internal concordant and discordant priming sites, respectively), and $info tables from the hdf5 file with an additional per-cluster entry $cluster.feature.counts table showing per-feature (rows) per-cluster (column) molecule counts (if cell.clusters are not supplied $info$cluster.feauture.counts will contain one column, 'all' giving dataset-wide counts)
