Hi everybody,

I have 552 .hea files and in each file i have a data named pH and the respective value.

I need to import this data from every file and then to create a vector with the pH of all the 552 files.

How can I do?

Thank you,

Francesca

Hi,

This answer mentions about reading the physionet data where the .hea files are explicitly resides. If the application of .hea files is different than that of physionet, I see that these are text files and can be read using fileread and then the content can be seperated as matrix that is mentioned as pH values.
