KIT layout for plots

Hi Veda,

Which version of mne do you use? I am using mne 0.15.dev0. I can import
your CON file and plot ICA components estimated using your data. To check
the version of mne:

import mne
mne.sys_info()

If the output information describes earlier version of mne (<=0.14), try
updating mne to the latest version might helps.

Best,
Kevin

Hi MNE experts,

I used KIT system for MEG data recording.
MEG data were imported to mne with two following functions:
raw = mne.io.kit.read_raw_kit(file, stim = [200],preload=True)
kit_lay = mne.channels.layout.read_layout('KIT-TW-157.lout')

However,I had problems with two following functions:

(1) ica.plot_properties(epochs, i)
      error message: "the KIT system with ID 261 is missing"

(2) mne.viz.plot_evoked_topo(evokeds, layout=kit_lay)
     no error message but caused the program to crash

Your suggestions will be appreciated. Thanks!

Best,
Veda

Hi

For the first error, it is likely due to a KIT specificity issue. Can you
open an issue in github, and upload a small chunk of your data so that one
of us check it out (perhaps Teon, Eric or Christian? I'm on the road
sorry.)

Thanks

Hi Kevin,

Thank you for the suggestions.
Somehow, mne.sys_info() did not get the version information but
mne.open_docs() did. I can confirm that I used MNE 0.15.
Besides, the function ica.plot_components(layout=kit_lay) do allow me to
plot plot the PCA components. However, the function
ica.plot_properties(epochs, i) did not work.

Thanks to Kevin's suggestion, using the following code solved the problem.

ica.plot_properties(epochs, i, topomap_args={'layout': kit_lay})
