So my team recently imported some cIEF data using a PA800 plus system. There are three pI markers in each injection that we would like to use to generate a slope and Y-intercept from the pI markers. I attempted to make a long, nasty custom field for this and there's one portion that I can't get to work.
We named the peaks PI_1, PI_2, and PI_3 in the processing method to designate the pI marker peaks. Here's the part of my custom field that I can't get to work:
(PI_1[Migration Time]-PI_Avg_MT)+(PI_2[Migration Time]-PI_Avg_MT)+(PI_3[Migration Time]-PI_Avg)MT)
The custom field for PI_Avg_MT is (PI_1[Migration Time]+PI_2[Migration Time]+PI_3[Migration Time])/3 and this CF works as intended.
Currently, we have custom fields working to utilize two of the three pI markers (following how Maurice cIEF data is used in Empower to utilize the pI markers via Waters Support). We were just trying to find a way to use all three pIs without success.
Let me know if I can provide any more information!
