Hi Sam,
I need to add a more informative error message - the problem is that
no
valid BAF values are reaching the call to CNA (baf.dat is NULL). This
could happen if the values of snp.ids or chrom.ids are invalid - these
should all be integer values matching the contents of snpID and
chromosome in the netCDF file. What values are you using for these
arguments?
You will need to have LRR in the intensity NetCDF file. A portion of
the code downstream from the error you're getting uses LRR to filter
potential anomalies.
