Dear researchers,

Very recently, I have downloaded the last version of IGMPlot, version 3.08. I found some new descriptors included in this very nice, complete, and versatile version. One of newly proposed descriptors is "qg" which makes 2-D plots colored based a given scale ranging from 1 (blue color) to 4 (red color). Please let me know the exact and straightforward meaning of these numbers and colors. Indeed, what is the practical usage of "qg" index? or, what is its interpretation when a given inter- or intra-fragment interactions is analyzed? I cannot understand what concept should be taken into account when a 2-D plot of delta_g_inter versus sign (lambda2*Rho) is colored from blue to red (from number 1 to 4). What practical information one can obtain depending on the color type of a given picke. For instance, a taller picke (a larger delta_g value) means a stronger interaction but what statement should be provided for a smaller (blue) or greater (red) value of "qg"? In advance, too many thanks for any help.

Best,

Saeed
