|This error occurs when the data set does not appear to be empty. Note that this may also be due to a wrongly formatted input set (e.g. no instrumental summary lines).|
|The number of input data sets to be merged exceeded the maximum number (currently set to 9).
corrective action: Only the first 9 number of input sets are processed.
|Normally one expects at least some of the sources in two input data sets to overlap, if this is not the case this warning message appears.
corrective action: The input sets should be checked by hand/eye whether the two should actually be merged together.
