I see - ok, great. Will amend that!

Thanks again,

Hi Nicola,
The archive specification is optional. So it should work with or without it. I think the problem is likely the duplicate slashes – “files//MNINonLinear”. I copied your curl command, and worked as-is once I removed the duplicate slash.

Mike

oh wait - I have and extra 'archive' in the path... is this what the problem is?

    Hi Michael,

    I am using:

    sub=100206
    h=R

    curl -u USER:PASS -O
    
https://db.humanconnectome.org/data/archive/projects/HCP_1200/subjects/${sub}/experiments/${sub}_CREST/resources/${sub}_CREST/files//MNINonLinear/Native/${sub}.${h}.sphere.MSMAll.native.surf.gii

    so the URL is the same (i think) but the curl options are slightly
    different... could this be it? I will try!

    Thanks for your reply,

    Nicola

        Hi Nicola,

        What URL are you using to retrieve the file via CREST/curl?
         When I do:

        curl -s -k --cookie JSESSIONID=$JSESSIONID
        
https://db.humanconnectome.org/data/projects/HCP_1200/subjects/100206/experiments/100206_CREST/resources/100206_CREST/files/MNINonLinear/Native/100206.R.sphere.MSMAll.native.surf.gii
        -o 100206.R.sphere.MSMAll.native.surf.gii
        
<https://db.humanconnectome.org/data/projects/HCP_1200/subjects/100206/experiments/100206_CREST/resources/100206_CREST/files/MNINonLinear/Native/100206.R.sphere.MSMAll.native.surf.gii%20-o%20100206.R.sphere.MSMAll.native.surf.gii>

        I get:

        4175821 Nov  2 11:45 100206.R.sphere.MSMAll.native.surf.gii

        with the following md5sum:

        5478269f6345c91c0566d7bccf010860
        100206.R.sphere.MSMAll.native.surf.gii

        The md5sum from the file I’m retrieving via CREST/curl matches
        what I get from the package.

        Thanks,

        Mike

        Hi list,

        though a processing error I noticed the following strange
        behaviour:

        1) When i download the complete structural package using the
        Aspera plugin and extract the file I am interested in, I get
        (for example):

        rwxrwxrwx 1 nicola users 4175821 Nov 27  2015
        100206.R.sphere.MSMAll.native.surf.gii

        and this file works fine

        2) When I fetch the same file through CREST/curl, I get a
        totally different file size (no error messages):

        -rw-r--r--        1 nicola users 213364 Oct 30 19:56
        100206.R.sphere.MSMAll.native.surf.gii

        and a parse error when I try to use it.

        Any Idea what I may be doing wrong?

        Thanks in advance!!!

        nicola
