FCS Scan provides an interface for locating FCS files from local or remote file systems and generating Workspaces from files located. In situations where your IT department moves whole directories, or you can’t remember where you stored a sample set it can really come in handy. This tool is also extremely useful for finding files from a specific date, operator, instrument, or any other FCS keyword.
The tool can be launched by clicking the FCS Scan icon from File tab of the Workspace.
To add files, drop a folder of files on the main window. If you wish to make add found files to the current Workspace, just select those files (click and drag over rows, Shift+click, or Ctrl/Cmd+click) and then select “Add to Workspace” from the file menu.
Shown below is the result of dropping a folder of files on the tool. Matching colored lines indicate duplicate files, which can be toggled on/off from the “Show duplicates” check box.
Like columns in the Workspace, you can customize the keywords displayed to help in identifying the samples of interest. New keywords can be added from the Workspace tab. In the example, we were mainly looking for a summary of which instruments were being used, but this could easily have been a specific patient ID, an operator, a run date, or any other combination of keywords.
Sorting by a specific keyword can be accomplished by double clicking a column header.
