How to download the HCP FIX-denoising data

[a1187551363]

I want to know how to use the command line in a Linux system to download data containing FIX-denoise, including the classification labels and files output by FIX.

Command line and our Aspera server don't currently work very well together, but a user found this approach to download packages:

For a more user-friendly way, we recommend mounting your network filesystem on a computer that you can run a browser with Aspera on (and has good bandwidth to both the internet and the network filesystem), and downloading packages that way.

We plan to implement a command line method to download single files rather than packages at some point.

Dear HCP Support Team,

I want to conduct some research using the IC and TC after ICA and the labels after FIX classification. I have downloaded data from the HCP Young Adult 2025 release.

For one subject, the directory structure under:

MNINonLinear/Results/
    rfMRI_REST1_RL
    rfMRI_REST2_RL
    rfMRI_REST1_LR
    rfMRI_REST2_LR

contains only the processed fMRI data, but I cannot find:

• ICA spatial maps (e.g., melodic_IC.nii.gz)

• ICA time series (e.g., melodic_mix.txt)

• FIX classification outputs or component labels

The 2025 release documentation mentions updated spatial and temporal ICA processing. I would like to confirm:

1. Are subject-level ICA component maps and FIX classification labels still publicly available?

2. If so, in which data package or directory can they be found?

3. Are they included in the S1200 Extensively Processed data, or provided separately?

4. Is there a recommended command-line or package-based method to download ICA outputs specifically?

My research requires access to the individual ICA components and their corresponding noise/signal labels.

Thank you very much for your guidance.

Best regards,
Tianye Chen
