MGH_0.7mm_DWI.src.gz.hcp1065.qsdr.1.25.R65.fib.gz     DWI data reconstructed to the ICBM152 space, ready to align with BigBrain and other ICBM152 space data

Method: A multishell diffusion scheme was used, and the b-values were 1000 and 2500 s/mm2. The number of diffusion sampling directions were 840 and 1680, respectively. The in-plane resolution was 0.76 mm. The slice thickness was 0.76 mm. The diffusion data were reconstructed in the MNI space at 0.5 mm using q-space diffeomorphic reconstruction (Yeh et al., Neuroimage, 58(1):91-9, 2011) to obtain the spin distribution function (Yeh et al., IEEE TMI, ;29(9):1626-35, 2010).  A diffusion sampling length ratio of 1.25 was used The output resolution of is 0.5 mm isotorpic. The restricted diffusion was quantified using restricted diffusion imaging (Yeh et al., MRM, 77:603–612 (2017)).

To track the data, download DSI Studio at and open the FIB.gz file in [Step T3 Fiber Tracking]. The figures were created by whole brain tracking of 500,000 tracks and cut at mid-brain and pons level using [Edit][Cut by slice][Cut Z+]


1. The source of the data was shared under CC0 license at 1 and 2, and I would strongly recopmmend acknowledging the data source to the reference (Wang et al at MGH)
2. The SRC and FIB data shared on this page were processed by DSI Studio and inhereted the same CC0 license. Please acknowledge Wang et al. at MGH and mentioned the data were processed in DSI Studio.
