[FieldTrip] Where can I get 4D layout for MEG result?

Tue Jan 31 22:36:27 CET 2012

I renamed '4D248.lay' to 'CTF275.lay' then checked with 'ft_layoutplot', it worked. 

If renamed 'CTF275.lay' to '4d248.lay', 'ft_layoutplot' showed error message.

So I think it must be some code error in reading layout file. 

Any suggestions? 

Thanks,
Duo

A very strange thing...

I tested the other layout, like 'CTF275.lay' using 'ft_layoutplot', it works. However, '4D248.lay' dosen't work on 'ft_layoutplot' with the same error message as before:
Error using dataread
Trouble reading floating point number from file (row 1, field 1) ==> <!DOCTYPE html>\n
....

Even I rename 'CTF275.lay' to '4D248.lay', it comes the same error message.

Any suggestions?

Thanks,
Duo

Dear Robert,

Thank you so much for the suggestion. I compared the file but couldn't get idea yet. The format of 4D248.lay which I am using is like follows:

1 0.23057 -0.26062 3 2.25 A1
2 0.23057 3.8119 3 2.25 A2
3 0.064345 8.2238 3 2.25 A3
4 0.064345 11.957 3 2.25 A4
5 -0.10188 16.0295 3 2.25 A5
6 -3.7588 16.0295 3 2.25 A6
7 -4.0913 11.957 3 2.25 A7
8 -4.2575 8.2238 3 2.25 A8
9 -4.0913 4.1513 3 2.25 A9
10 -4.2575 -0.09093 3 2.25 A10
....

Any more suggestions?

Thanks,
Duo

Dear Duo

The error suggests that the layout file is corrupt, DOCTYPE is not a string that should be present in the file. Please open it in a text editor and compare it with the format here http://fieldtrip.fcdonders.nl/faq/what_is_the_format_of_the_layout_file_which_is_used_for_plotting
