select all-maps
what about select the most top map instead of not select anything.
That will only work if you have a top level map. For other than single small caves I have avoided collecting all the maps into a single map, because it makes it more difficult to quickly change the scope or style of outputs directly from the thconfig or index file, and the resulting pdfs are less versatile. Multiple maps means many layered pdfs over which the end user has more control. I do collect together whole caves in larger systems, but, at the top level I tend not to collect more than one cave into any particular map. In addition, there seem to be times when even explicitly declared sub-maps that do not contain scraps or maps (ie contain surveys only) are not included in the output of their parent map. I have not got to the bottom of exactly what conditions cause this however, but it seems very similar to the issue described in my original post. Bruce
