Preprocessed Connectomes Project

The goal of the Preprocessed Connectomes Project is to systematically preprocess the data from the 1000 Functional Connectomes Project (FCP) and International Neuroimaging Data-sharing Initiative (INDI) and openly share the results. Initiated in 2011 with the ADHD-200 Preprocessed initative, the PCP has grown to include the Beijing Enhanced DTI dataset and ABIDE. To enable the comparison of different preprocessing choices and to accomodate different opinions about the best preprocessings strategies, most of the data is preprocessed using a variety of tools and parameters.

Data is currently hosted in an Amazon Web Services Public S3 Bucket and at NITRC. More information about downloading the data and about the various preprocessing pipelines and strategies employed can be found on the Datasets page. If you use PCP data in your research, please cite it in your publications along with the specific pipeline that you used. Also, please let us know about your publication so that we can add it to our list of Publications.

Assessing the quality of data and determining the data that should be excluded from an analysis due to poor quality is difficult. To help address this issue, we have developed a Quality Assessment Protocol and have calculated these metrics on the ABIDE dataset.

Please direct any comments or questions to the PCP Forum</li>. Also, please monitor the forum for updates and bug reports.
