Excuse me,when I run the file "analysis_FeaturePrediction.py",There was an error.as follows: `

` can you tell me some reasons?

The error is due to file format changes in our lab. I uploaded a data file (ImageFeatures.h5) which is compatible to the latest Python code. Please download it from http://brainliner.jp/data/brainliner/Generic_Object_Decoding, put it in your data directory, and try the script again.

Thanks for your reply, I will try the script again.thanks~

hello, i'm trying to load subject data (Subject1.h5) and I'm getting the same. error. Can you reupload the subject data in the compatible format as well? Thanks!

I have confirmed that the data file (Subject1.h5) is in compatible format.　 Please make sure that the data path and file size is correct. The file size of the Subject1.h5 is about 120MB, so if not, please download it again.
