.. _dig-formats:
Supported formats for digitized 3D locations
============================================
.. NOTE: If you want to link to this content, link to :ref:`dig-formats`
for the implementation page. The next line is
a target for :start-after: so we can omit the title above:
dig-formats-begin-content
MNE-Python can load 3D point locations obtained by digitization systems.
Such files allow to obtain a :class:`montage <mne.channels.DigMontage>`
that can then be added to :class:`~mne.io.Raw` objects with the
:meth:`~mne.io.Raw.set_montage`. See the documentation for each reader
function for more info on reading specific file types.
.. NOTE: To include only the table, here's a different target for :start-after:
dig-formats-begin-table
.. cssclass:: table-bordered
.. rst-class:: midvalign
================= ================ ==============================================
Vendor Extension(s) MNE-Python function

Neuromag .fif :func:`mne.channels.read_dig_fif`
Polhemus ISOTRAK .hsp, .elp, .eeg :func:`mne.channels.read_dig_polhemus_isotrak`
EGI .xml :func:`mne.channels.read_dig_egi`
MNE-C .hpts :func:`mne.channels.read_dig_hpts`
Brain Products .bvct :func:`mne.channels.read_dig_captrak`
Compumedics .dat :func:`mne.channels.read_dig_dat`
================= ================ ==============================================
To load Polhemus FastSCAN files you can use
:func:`montage <mne.channels.read_polhemus_fastscan>`.
It is also possible to make a :class:`montage <mne.channels.DigMontage>`
from arrays with :func:`mne.channels.make_dig_montage`.
