Description

# %%
import mne

montage_name = 'easycap-M1'

m = mne.channels.make_standard_montage(montage_name)
adj, ch_names = mne.channels.read_ch_adjacency(montage_name)

The read_ch_adjacency() call raises:

ValueError: "easycap-M1" is not a valid fname. Try one of:

['easycap128ch-av', 'neuromag306', 'KIT-UMD-3', 'biosemi64', 'bti148', 'easycap32ch-av', 'KIT-UMD-1', 'easycapM11', 'KIT-208', 'KIT-UMD-4', 'ctf275', 'easycapM14', 'ctf64', 'easycapM1', 'biosemi16', 'KIT-UMD-2', 'bti248grad', 'easycapM15', 'ctf151', 'bti248', 'neuromag306planar', 'biosemi32', 'easycap64ch-av', 'KIT-NYU-2019', 'KIT-157']

We should establish consistency here where possible

Research direction

Start by tracing mne.channels.make_standard_montage() and mne.channels.read_ch_adjacency() to compare their accepted montage identifiers, especially easycap-M1 and easycapM1. Determine which naming differences can be aligned, then verify that the same identifiers work consistently in both calls. The issue does not name specific files or tests, so locate the relevant implementation and test coverage first.
