I am using ICA to correct for blinks. Prior to running ICA, I am doing a bit of minimal data-cleaning so that my ICA is reasonably good. I rejected and replaced bad channels (kurtosis, threshold=4) and then am rejecting epochs based on an abnormal linear trend of greater than 150 (which I realize is quite generous). <div>
<br></div><div>What I don't entirely understand is the minR option that one has to set for the abnormal trend detection. The documentation says, cryptically, that it's the "minimal linear regression R-square value to allow in the data". What are we regressing? Is this mV against time? That is, is this a measure of how linear the trend is (1 = perfectly linear during the epoch)? </div>
