This module does not read flow cytometry standard FCS files.

Examples

Read the CountRateArray from a ConfoCor3 ASCII file as a numpy array:

>>> fcs = ConfoCor3Fcs('ConfoCor3.fcs')
>>> fcs['FcsData']['FcsEntry'][0]['FcsDataSet']['CountRateArray'].shape
(60000, 2)

Read data and metadata from a ConfoCor3 RAW file:

>>> fcs = ConfoCor3Raw('ConfoCor3.raw')
>>> fcs.filename()
'f5ee4f36488fca2f89cb6b8626111006_R1_P1_K1_Ch1.raw'
>>> fcs.frequency
20000000
>>> times = fcs.asarray()
>>> times[10858]
1199925494
>>> times, bincounts = fcs.asarray(bins=1000)
>>> times.shape
(1000,)
>>> bincounts[618]
23
>>> fcs.close()

Read data and metadata from a ConfoCor2 RAW file:

>>> fcs = ConfoCor2Raw('ConfoCor2.raw')
>>> fcs.frequency
20000000
>>> ch0, ch1 = fcs.asarray()
>>> ch1[4812432]
999999833
>>> times, ch0, ch1 = fcs.asarray(bins=1000)
>>> times.shape
(1000,)
>>> ch1[428]
10095
>>> fcs.close()
