Question regarding the templates

[hendrikrth]

Hi,
I have a question regarding the file ‘templates.npy’. I run Kilosort on my data which has 16 Channels with the following parameters:
ops.NchanTOT = 16
ops.Nchan = 16
ops.Nfilt = 64

The matrix in ‘templates.npy’ is of shape 64x82x16, the similarity matrix ‘similar_templates.npy’ has the shape 64x64. My question is now how are these two matrices related? How do I find out which template in ‘similar_templates.npy’ corresponds to the templates in ‘templates.npy’? And do I understand it correctly that the templates are local for each channel and in my case there are 64 on each of them?

Because you set ops.Nfilt = 64, Kilosort finds 64 templates. Each template is 82 time samples long, and covers all 16 channels. The first template is found in this way:

> temps = readNPY('templates.npy'); > template1 = squeeze(temps(1,:,:));

and so on. The similar_templates file has the similarity between each pair of templates, i.e. the similarity measure between template 1 and template 10 is given by:

> sim = readNPY('similar_templates.npy'); > sim1vs10 = sim(1,10);

Hth - I wasn't sure what you meant by "local for each channel" so maybe I didn't answer everything...
