The time counter is shown in the tool bar of the workspace window. Time Since Last Save to show the amount of time that has past since you saved this workspace. As is the case with using the Gene Pattern server, clustering outputs or other derived parameters can be appended to files in FlowJo via drag and drop onto the original file in FlowJo.The section marked Appearance defines preferences about the how the workspace appears. If your are facile with R, you can of course run the R algorithms directly in R and write the outputs as. Run FlowJo and the desired R tools in a script from the command line The event numbers must match, but this should be the case if it is the same file. To get these results into FlowJo, drag and drop the resulting CSV file onto the FCS file in FlowJo that you clustered. For clustering applications the results are usually available as comma separated value (CSV) files, which usually outputs a vector of cluster memberships separated by commas that programs like Excel or FlowJo can interpret. The results are then exported depending on the type of application. You can choose from several categories through the ‘Browse Modules’ option, and drag favorites to the selection box to the left. The picture below shows a screen shot of a the gene pattern server with the clustering modules section opened. You will need to create a user account, but its free. The gene pattern server can be accessed online. They create a web browser interface that only requires the user to answer a few questions to run the algorithm. Many of the tools in bioconductor have been made available to non-programmers by the Gene Pattern Server, a group based out of MIT’s Broad Institute. When that has been set up, every plugin you download and drop into the folder you selected will appear in the workspace plugin dropdown menu: Run the R tools from the Gene Pattern Server The exact path will vary based on your own particular selections: To use plugins in FlowJo you will have to go into the diagnostics tab within the FlowJo plugins and include the R path and the path to whatever folder you have put downloaded plugins in: ![]() As an example, this is the code to install flowSOM, a popular clustering algorithm: This is done through the command ‘install’. Some R derived plugins will require the user to install the program itself in R (also just one time) before using. To install the Bioconductor suite, simply open R and type (or copy-paste): if (!requireNamespace("BiocManager", quietly = TRUE)) Most R derived plugins require the bioconductor libraries, a suite of R tools developed by scientists working specifically with biological data. We are in the process of doing this, and you will note that some plugins include a notice that a specific version of the plugin is intended to be run if you have R 4.1.x and an older version of the plugin is needed if you are running R version 4.0.x. Important note as of : The R versions 4.1.x have significant changes to them that have required many R dependent plugins to be updated. R based plugins do not require you to know how to use R, but they do call R in the background to execute the script, and so you must have R installed on your computer. We do our best to stay current and work with the authors of algorithms that are frequently cited or requested by our users to create plugins. ![]() Many of the plugins are were originally developed as R-scripts where they gained fame and popularity. The FlowJo Exchange hosts plugins, additional tools that can be ‘plugged into’ FlowJo to expand its capabilities.
