<div dir="ltr">Hi Joe,<div><br></div><div>I agree with Chris - please send through a vex file + v2d file. Correlating complex data with real data should be fine, so I expect it might be an issue with compatibility of channel edge alignment or channel width or something.

This is really impossible to say without seeing the config files. Best to to tar up the minimum set of files needed to run vex2difx (the .vex and .v2d files at least and any files they refer to (e.g. filelists)<br>

I've tried the ANTENNA parameters addZoomFreq and zoom, and both seem to lead to this outcome. I see in the freqId parameter in the SETUP section a blurb about selecting a parent band, but I'm not sure how this is applied--after selecting the freqIds of interest, there's no change in the warning message. (As a note, I have to select the freqIds of both antennas here because I'm unsure of how to apply different setups for different antennas to a single source if that is possible).<br>

I should also note that I'm attempting to correlate complex data with real data, is this something that is supported in the current version of DiFX, or do I need to convert one of my datasets for compatibility? Any advice/expertise would be greatly appreciated!<br>
