Empower Custom Field

[anietyx0]

Is there a way to calculate the average peak % area of peaks greater than or equal to a certain threshold (e.g. greater than or equal to 0.05%, or GTE), peak by peak, between two samples and then sum those peaks on Empower (e.g. AVE(Peak1inSample1[PercentAreaGTE05] + Peak1inSample2[PercentAreaGTE05]) + AVE((Peak2inSample1[PercentAreaGTE05] + Peak2inSample2[PercentAreaGTE05]) + ...), possibly using custom fields with boolean expressions?

to solve the GREATER than, you can make a customfield which multiplies your result with the GT function:
if it's greater, your value is multiplied with 1, so your result stays, if not, your result is multiplied with 0.
