chn 0 giving me no feature and amplitude value #1184

Open fredchen00 opened 1 year ago

fredchen00 commented 1 year ago

I was trying to write some plug-in for phy but I noticed the feature value and the amplitude for channel 0 is always 0. It even shows up as zero in the feature and amplitude view. I am wondering if this is a code bug or am I doing something wrong. I performed my spike sorting through Spyking Circus. Thanks in advance image

Just want to make another comment, 0chn has feature values when I open its npy file. So somehow the value is lost in phy I think.

Just another note, I was able to trace the data flow. Somehow the feature value was set to zero after
features = from_sparse(features, cols, channel_ids) in line 1042 inside the get_features function in phylib/io/model.py
