Hi We decided to rename the demo data. This is a bit more complicated than I thought so I'm not able to do this now. Evgueni, can you? In CCPPETMR/data/Gadgetron git mv testdata_a2.h5 simulated_MR_2D_cartesian_Grappa2.h5 git mv testdata.h5 simulated_MR_2D_cartesian.h5 git commit ... in xGadgetron/examples edit all demos to replace names. Note that Grappa demo(s) currently use testdata.h5 as default which fails. Does the update.SH run "make" in this example? For non-VM users, you will have to explicitly call "make" in xGadgetron/examples (after "git pull" in CCPPETMR_VM) Kris
