This recording contains multiple ICP data blocks. In other words: it has gaps in the raw ICP data stream. This information is stored in waves/icp.index/ HDF5 node.

BTW This patient was also shunted.

Could you show pictures?

In our email communication, you mentioned that you suspected that this recording was upsampled from 50 Hz to 100 Hz. I don't think that upsamling was performed. It looks like this file was recorded naively with the sampling freq. of 100 Hz. Maybe the problems you experienced are not caused by low sampling frequency (x-axis resolution) but rather by relatively high quantization error (low y-axis resolution) w.r.t. the ICP amplitude. Moreover, this patient was shunted and ICP was measured via the reservoir. This may be the reason of poor quality of ICP waveform.
