将fMRI PMU文件加载到python中
fmri-physio-log的Python项目详细描述
解析MRI PMU（生理日志）文件
这个小库解析西门子PMU文件。这些文件是由西门子生理监测单元（PMU）生成的*.puls、*.resp、*.ecg和*.ext文件，类似于：
1 8 20 2 367 508 520 532 638 708 790 814 1037 1108 1072 1190 1413 1495 1695 ... ECG Freq Per: 0 0 PULS Freq Per: 72 823 RESP Freq Per: 0 0 EXT Freq Per: 0 0 ECG Min Max Avg StdDiff: 0 0 0 0 PULS Min Max Avg StdDiff: 355 1646 795 5 RESP Min Max Avg StdDiff: 0 0 0 0 EXT Min Max Avg StdDiff: 0 0 0 0 NrTrig NrMP NrArr AcqWin: 0 0 0 0 LogStartMDHTime: 36632877 LogStopMDHTime: 39805825 LogStartMPCUTime: 36632400 LogStopMPCUTime: 39804637

^{pr2}$使用
假设上面的示例日志文件（第一行被截断）称为sample.puls，那么我们有：
importfmri_physio_logasfpllog=fpl.PhysioLog('sample.puls')log.ts# array([ 508, 520, 532, 638, 708, 790, 814, 1037, 1108, 1072, 1190, 1413, 1495, 1695])log.rate# 20log.params# (1, 8, 20, 2, 367)log.ecg# MeasurementSummary(freq=0, per=0, min=0, max=0, avg=0, std_diff=0)log.puls# MeasurementSummary(freq=72, per=823, min=355, max=1646, avg=795, std_diff=5)log.resp# MeasurementSummary(freq=0, per=0, min=0, max=0, avg=0, std_diff=0)log.ext# MeasurementSummary(freq=0, per=0, min=0, max=0, avg=0, std_diff=0)log.nr# NrSummary(nr_trig=0, nr_m_p=0, nr_arr=0, acq_win=0)log.mdh# LogTime(start=36632877, stop=39805825)log.mpcu# LogTime(start=36632400, stop=39804637)# For convenience the start and stop times are available# as python datetime.time objects as welllog.mdh.start_time# datetime.time(10, 10, 32, 877000)log.mdh.stop_time# datetime.time(11, 3, 25, 825000)log.mpcu.start_time# datetime.time(10, 10, 32, 400000)log.mpcu.stop_time# datetime.time(11, 3, 24, 637000)
