Data used in publication: 
Koebernick, N., Daly, KR., Keyes, SD., George, TS., Brown, LK., Raffan, A., Cooper, LJ., Naveed, M., Bengough, AG., Sinclair, I., Hallett, PD. & Roose, T. (in press). 'High-resolution synchrotron imaging shows that root hairs influence rhizosphere soil structure formation'. New Phytologist.

Images are cropped from original volumes. 
8d old barley (Hordeum vulgare cv. 'Optic') roots growing in syringe barrels with Bullionfield soil (sieved to < 1mm).
2 genotypes were used: 'hairs' wildtype and 'no hairs' mutant. 2 moisture treatments were used: 'wet-dry' and 'dry'.
see manuscript for details on experimental procedure.

Filenames are Genotype (H / N) followed by moisture treatment (D / WD) followed by sample number (1-5), followed by image type (raw / soil / root), followed by x-, y-, and z-dimension, respectively.

'H' is 'hairs' wildtype
'N' is 'no hairs' mutant    
'D' is 'dry'
'WD' is 'wet-dry'
'raw' is greyscale image
'soil' is soil segmentation 
'root' is root and root hair segmentation
