*Created by: olesenm* I've restarted my effort from last Nov to begin migration from ADIOS1 to ADIOS2 (lost some time with API changes and other things along the way). I'm still trying to figure out why I'm not really generating data properly (files are too small) and thus figured on using `bpls` to try to understand what is where. `bpls -l file` shows me my variables and attributes, but using the `-d` or `--dump` core dumps with this type of throw: ``` terminate called after throwing an instance of 'std::invalid_argument' what(): ERROR: selection is not valid for single value variable v1, in call to SetSelection ``` I've reached all the way back and now started using the `examples/basic/localArray` etc, but in all cases I get the same core dump with `bpls`. Is there any other way to diagnose my file contents? /mark
