Error running .rda files in Gannet

Ask Anything!

I am a student studying brain imaging, and I have a question.
When running Gannet in MATLAB with .rda files, I receive the error message ‘“FoVHeight” is an unrecognized field name.’
Is there a way to resolve this issue?
Also, is there a method to convert .rda files to the TWIX (.dat) format?

Hi @ICH,

  • Are you using the latest version of Gannet (v3.3.2)?

  • No, one cannot convert .rda files to the TWIX format. You’ll have to re-export your data from the scanner.

Thank you for answering my question.

Yes. I’m using Gannet (v3.3.2)
Then, should we not use .rda files in Gannet?

If you’re able to do so, I recommend using TWIX files instead of .rda files.

I have a similar problem. Is there any other solution besides exporting raw data? In addition to off.rda, on.rda, and water.rda, how can I use gannet to read them?

Hi @Zhangren,

Please make sure you’re using the latest version of Gannet. If the error persists, let me know.

The OFF, ON, and water files should be loaded like this: MRS = GannetLoad({'off.rda', 'on'rda'}, {'water.rda'}); (Note that the OFF file must be entered before the ON file.)

Thanks for your prompt reply, the problem still exists, my gannet version is v3.4.0

Would you be able to email me (mam4041@med.cornell.edu) an example of your .rda data?
