Dear Bioconductorians, Can someone tell me if the returned index by pmindex() ordered by the position of the probes on the target sequence? If so, is it from 3' to 5' or the other way? Here's an example of the result: $"1423504_at" [1] 886892 626949 262157 850850 892792 91807 312389 [8] 923026 993970 231493 316615 Thanks a lot! Wenbin
