Stim — Files [patched]

Use timing_tool.py in AFNI to validate your files before running the full model. It catches those pesky "missing run" errors early! #Neuroscience #fMRI #BrainImaging #AFNI #DataScience Option 3: Hardware Simulation (Verilog/Atmel) Focus: Testbench stimuli for electronic design.

While theoretically robust, the practical implementation of STIM files has faced hurdles: stim files

"device_type": "TENS-Unit-Mk3", "amplitude_mA": 20.5, "pulse_width_us": 250, "frequency_hz": 100, "electrode_pair": "A-B", "duration_sec": 1800 Use timing_tool

This is where stim files get complex. A stim file must specify which electrode contacts are cathodes (negative, the site of neural activation), which are anodes (positive, the return path), and which are turned off. This "contact map" determines the shape and direction of the electrical field. the site of neural activation)
