Description

Dear Cyrille,

Could you help me to figure out what scales are used by Phy in the following views:

  • On the figure below you can see TraceView and TemplateView with spikes fitted with the template (in blue).

Screenshot_2020-12-10_20-38-48

I thought that Y axis of TemplateView is channel number, but as can be seen at TraceView, traces in channel 13 are selected, whereas TemplateView shows the template somewhere around value "4". In addition, Y axis is fractional (e.g. 4.5) and has negative values. Therefore it is unlikely a channel number.

  • Are scales of Y axis of AmplitudeView in uV for "feature" and scaling factor for "template" views?

  • In CorrelogramView X axis is in ms, but is Y - average correlation coefficient or firing rate or else?

  • Is Y axis in FiringRateView a frequency of firing?

Thank you in advance for clarification.

Sincerely,
Stan

Research direction

Start by inspecting the TraceView, TemplateView, AmplitudeView, CorrelogramView, and FiringRateView entry points and their axis-label or scaling documentation. Determine what each axis represents and document the answers for all views; the issue is done when the scale meanings are clear to users.
