Flow Cytometry Tools

This is a collection of flow cytometry tools which can be used for a bunch of useful tasks. There are several that we are working on here at Floreada, as well as some tools from other sources which we have found handy. All tools on this list are free to use, although some of the 3rd party tools do require you to sign up. None of the Floreada tools require a login or any information from you. If you have a suggestion for a tool that you would find helpful,please let us know. We are always open to hearing your ideas.

Flow Cytometry Analysis

Analyze FCS files for free in our web-based app. We support most FCS file types including FCS2.0, FCS3.0, and FCS3.1. Floreada.io includes all features needed for basic analysis including:


Floreada.io FCS Analysis Tool


If you would like to see other free flow cytometry analysis software, we discuss the pros and cons of several options here.


FCS Editor

Have you tried to change the name of your FCS file? Since it is embedded as a keyword, renaming a file is not a straight forward task. This simple web-based tool allows you to easily edit the name of your FCS file, as well as the names of the parameters in the file.

FCS Convert

Sometimes it is necessary to extract the data in an FCS file into a different file format in order to do analysis. A common example is converting the events in an FCS file into a CSV format to do statistical analysis with software platforms that use CSV. This a simple web-based tool to convert FCS files into CSV files.

FCS Merge

This is another simple tool that allows you to take multiple FCS files and merge them into one big FCS file that contains all the events together. This should be used responsibly but can be useful for some purposes. All files that are concatenated together must have the exact same parameters.
