Hi, I use python2 and Macbook to run the code, but I get the following error, could you have a look?

Many thanks.

It seems you're missing appropriate data files. Please try:

  1. create data directory at the same directory with the python scripts.
  2. download the following files from http://brainliner.jp/data/brainliner/Generic_Object_Decoding and put them in the data directory.
    • Subject*.mat
    • ImageFeatures.h5 (not 'mat' file)
    • If you've already have the files, please confirm they are valid (followings are md5 hash for the files)
      • 4d2104e1bbb86827b309af18ef030b29 Subject1.mat
      • 9892f5c840df5203291b3267dc6f6793 Subject2.mat
      • b2d8b5a62d1f1c8b47eb1ef7ae83d68c Subject3.mat
      • 8675f185cf52cc57421a4729fe514e87 Subject4.mat
      • 79aa4e1c71008b42340e0ac79be2ba64 Subject5.mat
      • e4f084088a9c3f391f1b093f70d29e8a ImageFeatures.h5
  3. run the script
