ASCII format Data File Standard for Flow Cytometry The flow cytometry data file standard provides the specifications needed to completely describe flow cytometry data sets within the confines of the file containing the experimental data. The principal goal of the Standard is to provide a uniform file format allowing files created by one type of acquisition hardware and software to be analyzed by another type. http://www.bioconductor.org/packages/2.12/bioc/vignettes/prada/inst/doc/fcs3.html, accessed May 29. 2013.
