How can I modify information of an edf file and save it to disk?

Hello,

I would like to modify a field (for example number of data records) from an edf file and then save it to the disk.

How can I do that? For some reason the method modifyHeader raises some warnings/errors.

Thanks a lot in advance!

Hello Mariella,

MathWorks offers a range of functions that provide support for working with EDF/EDF+ files.

The edfwrite command can be used to write or modify EDF or EDF+ files. And the "SaveEDF" function can be used to save an EDF file.

Please refer to the following documentation to know about the functions that provide support for working with EDF/EDF+ files under the "Datastores and Data Management" category in "Functions" tab:

• https://www.mathworks.com/help/signal/ai-for-signals.html

"SaveEDF" function:

I hope this resolves the issue you were facing.
