Read and compensate FCS operator

Description

read_and_compensate_fcs operator transforms and compensates FCS files to Tercen datasets.

Usage

Input projection	.
documentId	is the documentId (document can be a single FCS file, or a zipped set of FCS files and a compensation matrix)

Output relations	.
filename	character, the name of the FCS file
channels	numeric, one variable per channel in the FCS file

Details

The operator transforms FCS files into Tercen dataset and directly transforms the channels according to the compensation matrix. If the document is a ZIP file containing a set of FCS files, the operator extracts the FCS files and tranforms them into Tercen datasets.

For compensation, if a .csv file is included in the .ZIP file, it will apply this as compensation matrix. Otherwise it will try to use the compensation matrix in the header of the .FCS file.
