Will this work for analyzing multichannel EcoG data from rat cortex?

Hello,

I am analyzing multichannel ECoG data and I wanted to use the nitime package to analyze coherence amongst the channels in the beta frequency band. To create the time series object using the time series function, TR is required as an input.

To my understanding, TR in the fMRI literature refers to the repetition time or the time for which a stimulus is presented is presented.
Because I am working with ECoG data and not fMRI data, where no stimulus was presented, can set the TR as my sampling rate?

Will this still give valid results?

Thanks in advance.

Hi Ahmed - thanks for your questions. The TR is the sampling interval (usually specified in seconds), so (1/sampling rate) in Hz. If you use that, yes, the results should be valid.
