Warning: Escaped character '\U' is not valid. See 'doc sprintf' for supported special characters.

[juedec]

Hello,

I use Matlab version 2023 and automagic version 3.0.
When I launch preprocessing I get this warning signal, having carefully stored my data as indicated by the plug-in sprocessors
Can you help me ?

Thanks

Hi, it is difficult to say without knowing the data structure and selected preprocessing steps. Could you share a file of 1 subject e.g., via Dropbox or WeTransfer?

[juedec]

Hi, These are EEG data recorded with a 128-electrode EGI system, e poch sur EVENT DIN1 in -.1; 0.5s, referenced 129th electrodes, sample 1000Hz. Please find attached one of the document https://we.tl/t-45ueIUbVyV Thanks for you help Julie

Hi, you've shared a .set file. Do you also have the corresponding .fdt file? Without .fdt file that contains EEG data, loading of .set file is not possible.

[juedec]

No, I don't have the fdt files. The raw data are .mff files which are modified in EEGlab to .set and secondarily imported into automagic.

[ksgfan]

I think that something went wrong during conversion from .mff to .set. The .set file you've shared with me does not contain any data. See on image below:

Could you share the .mff file too?

[juedec]

Strange !

Yes of course, you can find it there https://we.tl/t-FAjA56oetl

Can I charge file on mff format ?

[juedec]

Hmmm, I found the .fdt file
https://we.tl/t-bJMOHstoVO

[juedec]

I retry with the /fdt in the fold
I have a new error message and i keep the same erro message concerning '\U' and sprintf

[ksgfan]

It seems that the .set file structure is already epoched, but the data in fdt file is not. That is why you get an error.

Maybe try to run the preprocessing on the mff file? Automagic can handle them too.

Please note that you have misc. channels in your data and you need them exclude them (Exclude Misc. Channels in Automagic).

[juedec]

Yes I did it and I have the same message error.
I don't found where is the '\U' ; '\P'; Could it be a java or matlab version?
or directory?

fileio extension is not installed. Close Automagic, restart matlab, run restoredefaultpath in matlab command window, and run automagic again. It should install required extensions automatically, after you start the preprocessing.

[juedec]

It looks much better indeed, but I still have the same problem at the end ...

Hi, the dpss function is missing, which is part of the Signal Processing Toolbox. When you start Automagic, you should get a warning that this toolbox is missing. Simply install it in Matlab (Home -> Add-Ons -> Signal Processing Toolbox)
