Hi experts,
Me again. In trying to solve my question regarding the numbers in eddy_parameters, I tried eddy_quad and saw something concerning in the outlier distribution on the last page.
My output is here: https://drive.google.com/file/d/1JhGi2bzeHLFXHJ-R-9wPeJIqeTmvomWO/view?usp=sharing
The first and second half are extremely different - in the first half slices skew almost exclusively negative, and the second half is predominantly positive. I saw on the eddy documentation that positive outlier slices are uncommon, and it isn't recommended. I get that positive outliers can occur, but I am wondering why they only really occur in the latter half.
I am worried this is an issue with our acquisition/correction scheme. We collect two identical acquisitions (1 b=0, 32 b=700, A>P) and concatenate them for analysis.
Help would be much appreciated, thanks.
Josh
