Validate fileset dialog

• In the top panel we specify the data: either a binary or standard fileset. Here we see the example fileset listed. If other filesets were in the project, the combo box could be used to select one of them. Additionally, the individual files (BED, BIM and FAM) can be individually specified instead (i.e. if they do not share the same file root, or if they reside in a directory folder other than the main project folder). Alternate phenotypes can also be specified here.
• Options specific to the particular analysis appear next. In this case there are none.
• At the bottom, we see a place to enter the root filename for the output -- this must be a unique name (gPLINK will tell you if it is not, stating that it is an invalid fileroot). There are also options to filter or apply thresholds here, as we shall see later
