Hello everyone,
I?m currently working with the dataset and have noticed some discrepancies that I?d like to clarify. According to the original paper, the dataset should include samples with both EEG and MRI data in the following quantities:
AD: 35
bvFTD: 19
HC: 42
However, in the database, I?ve only been able to locate files for:
AD: 32
bvFTD: 18
HC: 40
Furthermore, among these files, only the following samples could be successfully read for EEG data:
AD: 19
bvFTD: 5
HC: 9
Has anyone else encountered similar issues? I?m trying to determine whether this is due to data missing or potential corruption, or if there?s something I might be overlooking in the data retrieval process.
Any insights or shared experiences would be greatly appreciated!
Thank you in advance.
Created by Huang Rui RumRed I did quick check, many files doesnt have actual file with data (fdt) only of metadata
| folder_0 | folder_1 | total_files | loadable_files | loadable_percentage |
|:-----------|:-----------|--------------:|-----------------:|----------------------:|
| 1_AD | AR | 16 | 16 | 100 |
| 1_AD | CL | 19 | 19 | 100 |
| 2_bvFTD | AR | 13 | 13 | 100 |
| 2_bvFTD | CL | 6 | 6 | 100 |
| 3_PD | AR | 7 | 7 | 100 |
| 3_PD | CL | 22 | 21 | 95.45 |
| 5_HC | AR | 19 | 19 | 100 |
| 5_HC | CL | 27 | 13 | 48.15 |
the exact files that gives me problem are:
'sub-100013', 'sub-100019', 'sub-100023', 'sub-100025', 'sub-100027', 'sub-100032', 'sub-100036', 'sub-100039', 'sub-100040', 'sub-100041', 'sub-100042', 'sub-100044', 'sub-100045', 'sub-100046']
I excluded early the folder 4_MS as was not relevant for my analysis
sub-40015 in the 3_PD CL folder has badly named set file, it has `s00415_CH_PD_reject.set` which preventing (in my case mne) from finding fdt file (the 4 is removed from the beginning of the ID identifier), and the fdt name should be also edited as it contain 4 in different place in filename
