The raw data import error

1

Hello,
I just encountered a problem that when reviewing raw file of Axion Axis, the software will report an error.
Who can tell me how to solve that. Thanks very much!

Hi @luying2650

  1. With Brainstorm started, could you run which AxisFile and paste the answer.

  2. Could you verify that the axion plugin is installed and loaded?
    Plugins > I/O > axion
    It should have a green button

Best,
Raymundo

Thanks, the axion plugin is loaded but the problem still exists.
And what do you mean by which Axisfile and how to run it?
Thanks

Start Brainstorm, then in the Matlab Command Window type the command below, and let us know the outcome

which AxisFile

Thanks. After I type which AxisFile in the command window, the outcome is " can't find AxisFile".
I somehow download the AxisFile on the internet and add it in the path of the software, but I still can't review the raw file of Axion Axis.

This is the error it shows.

Brainstorm can automatically handle the plugins and all the required files. Try the following:

  1. Remove the AxisFile that you downloaded from the path

  2. Update the Axion plugin to reset the plugin (Menu Plugins > I/O > axion > Update)

  3. Try to import the raw data

Thanks , I have updated the axion plugin but I still can't import the raw data.

It seems to be related to the .raw data file

  • Can you open this file with the axion software?
  • Can you try with other .raw files?

  1. Please check that you can open this .raw file with the AxIS software (check that the file itself is not corrupted)
  2. If it works, start Brainstorm, load manually the Axion plugin, and try executing in the Matlab command window the following code: FileData=AxisFile(‘Filename.raw’)
  3. Copy-paste the complete output of this command here
  4. If there is any error, it means that there is a bug in the AxisFile function, which is distributed and maintained by the Axion Biosystems company. We will need to contact the customer support of the company to get help with this.
  5. Try the same thing on the computer in which the AxIS software is installed, as you might have access to a newer version of the Axion library than the one distributed with Brainstorm. Follow the instructions from this document: AxIS Data in MATLAB. 1. Objective. 2. Importing AxIS Data into MATLAB. 2.1 Load all file data - PDF Free Download
  6. Only if there is no problem with the .raw file but a bug in the AxisFile function: upload the .raw file somewhere and post the download link here, so that we can share it with the Axion customer support.
