Testing fixed-pipeline spatial structure for <i>strong</i> task contrast (Task vs. Control).

<p>(A) DISTATIS-space plot, showing the similarity in spatial structure of optimal fixed pipeline SPMs; pipelines with overlapped 95% confidence ellipses have non-significantly different SPMs in this space. Cluster numbering is consistent with <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031147#pone-0031147-t002" target="_blank">Table 2</a>, and labelled with preprocessing steps that are consistent across all pipelines in the cluster, abbreviated: ICA with the MELODIC algorithm (<b>ICA_M</b>), motion correction (<b>MC</b>). See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031147#pone-0031147-t002" target="_blank">Table 2</a> for the corresponding list of pipelines. (B) mean activation maps, from a representative pipeline of each cluster: {MC,DET2}, {ICA_M,DET2} and {ICA_M, MC,DET2} (top to bottom).
