Hi Joelle,

The r227 is the newer, improved version. On the HCP Issues wiki 
<https://wiki.humanconnectome.org/pages/viewpage.action?pageId=29589520> :

 

Image reconstruction algorithm versions 
Two versions of the image reconstruction algorithm applied to dMRI and fMRI 
data have been used in HCP to date: version r177 for subjects scanned in Q1 
through mid-Q3, version r227 for subjects scanned mid-Q3 and after.  We were 
able to retroactively recon all dMRI data using the newer r227 version. 
However, for the fMRI data, this was not possible and data reconstructed with 
both r177 and r227 versions remain in ConnectomeDB. The reconstruction version 
makes a notable signature on the data that can make a large difference in fMRI 
data analysis. Users wanting to use only data with the same reconstruction 
algorithm applied in their analyses can filter data on the ConnectomeDB 
dashboard by fMRI reconstruction version (in the Study Completion category). 
See Ramifications of Image Reconstruction Version Differences 
<https://wiki.humanconnectome.org/x/RQBJB>  for more details.

 

Best,

Jenn

Hi Jennifer,

 

Thanks a lot for your help, that's really useful.

 

With regard to the reconstruction - I just wanted to clarify, and apologies if 
this is in the manual but I did not find it - When I filter by 'Study 
Completion' > 'Image Reconstruction' > 3T MR fMRI recon, I have 2 options - 
r177 and r227. 

 

Which is the more recent/ considered 'better' reconstruction method?

 

I suspect that the r227 is better if I am interested in using both diffusion 
MRI data and fMRI data, as the r227 is available for both, whereas r177 is only 
available for fMRI data, and not for dMRI. Is that correct?

 

Thanks,

Joelle

Hi Michael and Jennifer,

 

Thank you both for your help, much appreciated. One remaining question - is 
there currently any cutoff for cognitive scores (i.e. for the MMSE for ex) for 
subjects being included in the 500 release dataset?  Can't find mention of it 
in the ref manual, so Im guessing probably not.

 

Thanks,

Joelle

Hi Joelle,

All the HCP subjects are considered healthy young adults with no diagnosed 
cognitive abnormalities. They do, of course, have a range of abilities and 
scores on the behavioral tests we conduct. 

 

There is a lot of information in Chapter 1 of the current 500 Subjects 
Reference Manual 
<http://humanconnectome.org/documentation/S500/HCP_S500+MEG2_Release_Reference_Manual.pdf>
  for navigating the behavioral data and for filtering subjects—please check it 
out. There is also a  “Download CSV button” at the upper right of the subject 
Dashboard that will allow you to download all the open access behavioral data 
in one spreadsheet. Look at the sections of the Reference Manual on Restricted 
access data to see if you need to apply for access to that data for your 
purposes.

 

As detailed in the Introduction section of the Reference Manual, subjects that 
were originally acquired or released in different quarters/releases can be 
combined in analyses because we ran all subjects through the same analysis 
pipelines as of the 500 subjects release (as long as you are using data 
currently in ConnectomeDB, the S500 Connectome in a Box, or S500 S3 Bucket 
data).  Again, as stated in the Ref Manual Introduction, one thing you should 
be aware of is that the fMRI data collected in Q1 and part of Q2 was 
reconstructed with a slightly different reconstruction algorithm than 
subsequent data. You can filter on Study Completion>Image Reconstruction Info: 
3T MR>3T MR fMRI Recon Version, if you think it might make a difference to your 
analyses. 

 

In the upcoming 900 Subjects release (coming within the next couple of weeks!), 
the new subject data will also be comparable to the 500 Subject release data. 
Pipeline changes since the S500 release have been mostly minor and have only 
added to the data available (more details to come). 

 

Best,

Jenn

Subject: [HCP-Users] Demographic and behavioral subject data

 

Hello everyone,

 

I want to pick a group of subjects from the 500 subjects +MEG2  for which I 
will perform (rsfMRI and dMRI) analysis. These should be young, healthy, 
subjects that have no abnormalities and cognitively able.

 

Does anyone have any pointers about how I can go weeding out subjects? Under 
"Subject Information" of all subjects, I can see a list of all subjects, where 
I can see age, release and gender. And when I click on the subject, I find a 
bunch of behavioral tests and their results for that subject.

 

Should subjects from different releases be combined? Which is the most recent 
release?

 

Are there certain scores for cognitive assessments that are considered to weed 
out the cognitively able, healthy subjects? Is this data available somewhere in 
a spreadsheet form, without having to go into each subject and scrolling though 
their various assessment scores?

 

Anything would help.

Thanks,

Joelle
