All I can say that it might be that for some datasets I made a mistake when extracting hippocampal data from a complete dataset that included entorhinal cortex and removing bad channels (to reduce size and make more homogeneous). Full dataset is later uploaded as hc-3. You should be able to find very same data without any reduction there.  Data processing was performed using NDmanager plugins and particular processing parameters should be in the original hc-3 xml files. If I am remembering right back then we didn't use median filter yet for high-pass filtering, and it was done using compiled matalb firfilter function (attached). Call would be  firfilter $base.dat $base.fil $nChannels $samplingRate $lowestFrequency $highestFrequency $filterOrder 1 $offset with parameters specified in the xml file plugins section.   best Anton No publisher sirota 2018-03-14T08:37:23Z Comment https://crcns.org/forum/using-datasets/560389487/676204054 Hi Davide, if nChannels is correct (31 might be correct if there was a bad channel that I removed), than one problem I see in your code is the spike waveshape alignment:  timestamps in Res file are not aligned to the beginning of the spike waveshape, but sample 16 (see SpikeGroups/Peak sample field in the xml file). So the waveshape would be Data_H(1,236-16:236+15) best Anton No publisher sirota 2018-03-08T02:38:02Z Comment https://crcns.org/forum/using-datasets For questions or comments about using any of the data sets.
