Processing time of FastCSR, FreeSurfer and FastSurfer. The bar graphs illustrate differences in the average processing time for the validation dataset using FreeSurfer, FastSurfer and FastCSR. We compared the processing times for the surface reconstruction step alone (surface recon) and the whole pipeline including all necessary preprocessing steps for surface reconstruction using either sequential or parallel processing, the latter of which processes both hemispheres simultaneously. Among the three methods, FastCSR achieved the highest computational efficiency for the surface reconstruction step (5.22 ± 0.92 min and 2.61 ± 0.46 min for sequential and parallel processing, respectively), as well as for the whole pipeline (7.05 ± 0.92 min and 4.44 ± 0.46 min for sequential and parallel processing, respectively). Error bars indicate standard deviations
