Question about the Alleninf toolbox

I have a problem when I use the Alleninf toolbox (https://github.com/chrisfilo/alleninf).
My question is that I found the Alleninf just output the Averaged slope across donors (the last line, see below), how can I get the r/beta value in each donor?

Thanks in advance!

Averaged slope across donors = 0.199818 (t=2.34575, p=0.0659077)

Currently, this is not possible without modyfing the code. However, this modification should be easy - the relevant lines are here: https://github.com/chrisfilo/alleninf/blob/master/alleninf/analysis.py#L26

BTW alleninf is deprecated in favour of the gene decoding functionality built into NeuroVault.org (although it also does not show values for each donor).
