Hello,
I'm attempting to create clear figures out of my differential tractogram results by color-coding the tracts according decreased QA (dec_qa). This figure from your differential tractography paper looks fantastic:
However, when I scale the tract color, I'm not sure what my scale means:
The minimum is 0, and the maximum is 3.5, but is this a decrease in the actual value of QA or a percentage change? I'd like to change the color scale so that the min. value (blue) is 15% (the QA change threshold I used) and the max. value (red) is something near 100%.
Additional question: When rendering color, do you prefer to use the 'Max Index', 'Averaged Index', or 'Local Index' in certain situations?
Thank you for your time!
Noah
