Marta Meschini FCM Wizard is a flow cytometry data processing software program that was created in the late 1990s and early 2000s. Its development has since ceased, and its creators no longer maintain the program. The software may, however, continue to function on older operating systems or with older versions of other necessary software programs. It should be noted that using outdated software may result in compatibility problems, security threats, and decreased usefulness. As such, it is suggested to use contemporary flow cytometry data analysis software that is presently maintained and updated by its creators.
