A bug was found when using a tab-delimited file that had blank ("\t\t") column headers in the linear modelling component. The error was a JavaScript error so the options panel would not open and there was nothing in the interface to express what went wrong.
In the case that this bug was found, the previous component was a join component. The component appeared to create extra columns that were completely blank. Ask Paulo's student Cameron for more info on the input files.
There are likely other errors in components when there are empty column headers in a file. For instance, the column remover component does not display the blank columns in its options panel. We need to warn the user that these blank column headers will cause trouble and try to handle them wherever possible.
