FITMASTER NEXT
FITMASTER NEXT facilitates the advanced analysis of electrophysiological data. Its workflow allows you to clean raw data, perform comprehensive trace analysis with measuring tools, create trace fits, detect events, and analyze series of datasets.
Versions
Software updates are available free of charge. If a "dongle" is not connected to the computer, the program will run in demo mode. To avoid any compatibility issues, it is strongly recommended that you review the release notes before updating any software.
Please note:
- Due to a change in the file format, data created by PATCHMASTER NEXT versions 1.3 up to 1.5.2 can only be opened with FITMASTER / PATCHMASTER version 2x92, and vice versa.
- Read the Data Conversion Guide (see below)!
-
FITMASTER version 2x91 (or older) is not compatible with macOS 10.15 or later.
