I wanted to run lalinference_nest on some GWF files I already had available. With "lalinference_nest --help", it doesn't tell me how to actually do this, but from somewhere I thought the necessary flag was "--glob-frames". This was wrong, and when running the program, it warned me that I should pass an additional "dataseed" flag. However, it did not complain about the erroneous flag. Maybe it's not a bug but as a feature request, I think it would be good if the program gives an error or a warning when an illegal or unrecognized flag is given. Now, I had to actually look at the source code to find out that the flag I gave was an error and the correct flag is: "--glob-frame-data".
