FlowSOM combined with t-SNE for CyTOF data analysis

Ions are accelerated through the spectrometer in pulses. The electron cloud generated from a single cell is typically 10-150 pulses. The output of a Helios™ run is a binary integrated mass data (IMD) file that contains electron intensities measured from the ions for each mass channel. The continuous pulses must be resolved into individual cell events corresponding to the ion cloud generated from one cell. Each bin of between 10-150 pulses that passes the user set lower con… http://cytoforum.stanford.edu/viewtopic.php?f=3&t=1488 green shield pharmacy intervention codes
