README
## BrainIAK-SRM BIDS app
Shared Response Model (SRM) from the
[Brain Imaging Analysis Kit (BrainIAK)](https://github.com/brainiak/brainiak).
### Description
The Shared Response Model (SRM) is a method for aligning fMRI scans from several
subjects by assuming similar functional behavior in the brain. The voxels of
each subject are mapped to voxels of other subjects by projecting the
information from each subject into a low-dimensional space.
### Documentation
http://brainiak.org/docs/brainiak.funcalign.html
### How to report errors
Open a GitHub issue in [BrainIAK](https://github.com/brainiak/brainiak) (if the
issue is about SRM) or here (if the issue is about this wrapper app). We also
welcome all kinds of
[contributions to BrainIAK](http://brainiak.org/docs/contributing.html).

### Usage
This App has the following command line arguments:
usage: run.py [-h]
[--participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...]]
[--run RUN] [--task TASK] [--preproc PREPROC] [--mask MASK]
[--iterations ITERATIONS] [--features FEATURES]
bids_dir output_dir {participant,group}
Shared Response Model runner
positional arguments:
bids_dir Input directory
output_dir Output directory
{group} Level of the analysis that will be performed
optional arguments:
-h, --help show this help message and exit
--participant_label PARTICIPANT_LABEL [PARTICIPANT_LABEL ...]
Labels for participants to be analyzed (default: None)
--run RUN Run to be analyzed (default: 01)
--task TASK Task to be analyzed, default is any (default: *)
--preproc PREPROC Preprocessing tag, default is any (default: *)
--mask MASK Mask tag (default: bmask)
--iterations ITERATIONS
Number of iterations, default is SRM default (default:
None)
--features FEATURES Number of features, default is SRM default (default:
None)
### Special considerations
This app requires preprocessed data with all volumes of a subject registered. It
also requires masks to be present in the input data; all to-be-analyzed volumes
of a subject must use the same mask.
SRM works only on group level because it is a method for aligning fMRI scans
from multiple subjects.
The data must be time-synchronized, i.e., all subjects must be presented with
the same stimuli with the same duration in the same order.
Multiple runs and tasks can be given ("\*") if the number of voxels is the same
within subject (the number of voxels can differ across subjects).
