res.filt.mode
: the filtering method, either 'perc' or 'size', default will be size.
perc : genes projected onto mgs are only kept if they exceed a threshold percentage of the mgs size
size : genes projected onto mgs are only kept if they exceed a threshold number of genes
res.filt.threshold
: the threshold used to retain an mgs according to the filtering mode, either 'perc' or 'size'
if 'perc' : the minimal percentage of genes projected onto mgs (number of genes projected / mgs size) needed to select a mgs
if 'size' : the minimal number of genes projected onto mgs
