Single template

[yagui]

Hi,

I used spyking-circus to "sort" a single unit which gave me a single template.
I was having trouble to load this dataset into phy and I tracked down the problem to this line

phylib/phylib/io/model.py

Line 476 in 3e4dfb9

return read_array(path, mmap_mode=mmap_mode).squeeze()

The problem arise because read_array returns an array of shape (1,91,4) and then the squeeze method changes it to just (91,4).
And then this line gives the error

phylib/phylib/io/model.py

Line 710 in 3e4dfb9

assert cols.shape == (n_templates, n_channels_loc)

just after 'Loading templates' and 'Templates are sparse'

I tried exportingfrom spyking-circus to phy without sparse matrices and now it fails in this line

phylib/phylib/io/model.py

Line 434 in 3e4dfb9

assert self.similar_templates.shape == (self.n_templates, self.n_templates)

after 'Loading the inverse of the whitening matrix.'

If I remove the 'squeze' I can load this dataset of only one template, and also I didn't have problems with any other dataset sorted with spyking-circus, but I can not load anymore datasets sorted with kilosort2.5.
With kilosort output it fails in this line, just after 'Start capturing exceptions'

phylib/phylib/io/model.py

Line 647 in 3e4dfb9

assert samples.ndim == times.ndim == 1
