Hi Lars, First, welcome to OpenDX! Sounds like you've gotten quite a long way already. You may be interested in the OpenDX forum at http://www.opendx.org/cgi-bin/forum/YaBB.pl It gets more readers than the mailing list, I think.

Your original compute expression is probably correct (at least, it would not be the cause of that error message). The problem is upstream of Compute. Somehow, the number of positions received by Compute's a input is different from the number of data values received by the b input.
