Unrecognized function or variable 'astra_create_proj_geom'

[msolive1985]

I am testing the modules, and all the demos work, except for the 'demo_astra_2d'. Please see below the exception:
"Unrecognized function or variable 'astra_create_proj_geom'.

Error in demo_astra_2d (line 56)
proj_geom = astra_create_proj_geom('fanflat', dw*N/p, p, ..."

Any suggestions? Thanks!

Hi - great to hear the demos work. That particular demo illustrates how AIR Tools II can be used together with the ASTRA Tomography Toolbox, which needs to be installed separately, please check:  http://astra-toolbox.com/
