If the data do not match the exact chan_ids set in control file, then fourfit will not process anything but still continue to produce output. alist files become malformed with blank columns and this can break downstream parts of the pipeline. It can be difficult to uncover what the initial problem was at this late stage. Some earlier check should be done to flag this failure condition so the user knows to provide correct chan_ids.
