Calculate_​variable_​DIA_​windows

Calculate variable DIA windows from MS1

Calculates the sizes for DIA/SWATH windows depending on the intensity of MS1 data from DDA runs (AKA variable or dynamic DIA). The DDA files must be in mzML format (use ThermoRawFileParser or msConvert to convert vendor files). If the files are not peack-picked (controided), this will be performed by the workflow.
