- ## MRI quality control: Running MRIQC
- ### Overview
- > MRIQC extracts no-reference IQMs (image quality metrics) from structural (T1w and T2w) and functional MRI (magnetic resonance imaging) data.
- Please see the [official MRIQC documentation](https://mriqc.readthedocs.io/en/stable/) for details and refer to the paper listed in the References section.
- #### Data availability
- The data is freely available from https://github.com/lnnrtwttkhn/highspeed-mriqc and https://gin.g-node.org/lnnrtwttkhn/highspeed-mriqc.
- #### License
- The dataset is licensed under Creative Commons Attribution-ShareAlike 4.0.

- ### Container: `mriqc` container, version 0.15.2rc1
- MRIQC quality control was performed using [`mriqc`](https://mriqc.readthedocs.io/en/stable/), version 0.15.2rc1.
- To run MRIQC, we created a Singularity container based on the MRIQC docker image:
- ``` bash
- singularity pull docker://poldracklab/mriqc:0.15.2rc1
- ```
- ### MRIQC subject-level reports: `highspeed-mriqc-subject-level.sh`
- First, MRIQC has to run on the individual subject-, (if available, session-), modality- and run- level.
- This is achieved by running the `highspeed-mriqc-subject-level.sh` shell-script.
- The script is parallelizing all subjects and sessions on the cluster.
- ```{bash, echo=TRUE, code=readLines(file.path(path_root, "code", "mriqc", "highspeed-mriqc-subject-level.sh")), eval=FALSE}
- ```
- ### MRIQC group-level reports: `highspeed-mriqc-group-level.sh`
- Afterwards, one can run the `highspeed-mriqc-group-level.sh` script to acquire group statistics of the quality metrics.
- ```{bash, echo=TRUE, code=readLines(file.path(path_root, "code", "mriqc", "highspeed-mriqc-group-level.sh")), eval=FALSE}
- ```
