Convert MQD to another file type
To convert MQD data files to another format, you need FCS Express or other Data software.
Convert a file to MQD
To convert other file formats to the "Flow Cytometry Data" file type, you need software like FCS Express or a similar tool.
About MQD files
The .MQD file format primarily stores flow cytometry data generated by MACSQuant Analyzer instruments, developed by Miltenyi Biotec. Secondary uses include survey questionnaire data for HMMole software and Master Data Queue JSON command logs for the IzzyMaster Platform. Researchers rely on these files to analyze cellular characteristics, but the format presents significant workflow hurdles.
The .MQD format is highly proprietary when used for flow cytometry. It locks your experimental data into a vendor-specific ecosystem, often requiring expensive software licenses like FCS Express to open or analyze the files. These files are typically large, complex, and unsupported by standard web browsers, text editors, or open-source data science tools like R or Python.
Users frequently need to convert .MQD files to the universal FCS (Flow Cytometry Standard) format or CSV for independent analysis and collaboration. If your file is a survey questionnaire or a command log, converting it to TXT or JSON makes the data universally readable.
Because flow cytometry data uses closed binary structures, this file format is difficult to open or convert directly. Often only the original instrument software can properly export the cellular data. However, just drag and drop your file to convert.guru to identify the exact format, view its internal structure, and convert it if supported. If our analysis detects underlying standard text or an embedded JSON log, viewing or extraction may still be entirely possible.
Convert.Guru analyzes your MQD file, detects the exact format, and lets you read the text inside.
If you want to convert MQD file to FCS, you can use FCS Express or similar software from the "Flow Cytometry Data Storage" category. In the File menu, look for Save As… or Export….
To convert files to MQD, try FCS Express or another comparable tool in the "Flow Cytometry Data Storage" category.
The MQD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MQD converter.
