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 File 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.

FCS File Strip

If you need to make your FCS files public but would like to remove all identifying information stored in the file's keywords, this tool will strip out those keywords while keeping the keywords required to view the file's data.

FCS to CSV File Converter

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.
