mne_map_data
Overview
mne_map_data maps evoked data between sensor arrays via forward/inverse operators. It source-localizes the input evoked data using the inverse operator, then projects the source estimate through the forward solution (with target sensor geometry) to produce mapped evoked data on a different sensor array.
This is a C++ port of the original MNE-C tool by Matti Hämäläinen.
Usage
mne_map_data [options]
Options
| Option | Description |
|---|---|
--from <file> | Source evoked FIFF file |
--to <file> | Target measurement info FIFF file (for target sensor layout) |
--fwd <file> | Forward solution FIFF file |
--inv <file> | Inverse operator FIFF file (optional; computed from fwd if omitted) |
--out <file> | Output evoked FIFF file |
--snr <value> | SNR for regularization (default: 3.0) |
--help | Print help |
--version | Print version |
Example
# Map evoked data from one sensor array to another
mne_map_data --from source-ave.fif --to target-raw.fif \
--fwd sam-meg-fwd.fif --out mapped-ave.fif
# Map with explicit inverse operator and custom SNR
mne_map_data --from source-ave.fif --to target-raw.fif \
--fwd sam-meg-fwd.fif --inv sam-meg-inv.fif \
--snr 2.0 --out mapped-ave.fif
