To convert an ECG that has been encoded using MFER back to ECG format, you will need to use a software program that supports MFER decoding. There are several commercial and open-source software programs available that can decode MFER-encoded data, including WFDB (Waveform Database Software Package), PhysioBank, and the MFER Decoder Toolkit.
Install WFDB software on your computer.
Open a command prompt or terminal window and navigate to the directory where the MFER-encoded ECG file is located.
Use the "rdsamp" command in WFDB to decode the MFER-encoded ECG file and convert it to ECG format. The command syntax is as follows:
rdsamp -r [filename] -f [format]
Replace [filename] with the name of the MFER-encoded ECG file, and [format] with the desired output format (e.g., EDF, MIT, or WFDB).
Press Enter to execute the command. The software will decode the MFER-encoded ECG file and save it in the specified output format.
