Hi All,
I’m having problems loading our development scan MEGAPRESS data into Osprey. Our PRESS data works fine, as does our HERMES data.
I’m not sure whether it’s a problem with the acquisition, the data itself, or the job file set up. Any help would be greatly appreciated.
We have collected two separate voxels (dorsal striatum and parieto-occipital cortex) but the acquisition protocol (excluding voxel dimensions) and errors are identical for both so I have included only the information for the striatum voxel below for simplicity.
When trying to load the data into Osprey I get the following error:
Array indices must be positive integers or logical values.
Error in osp_plotLoad (line 299)
if nAvgs > dataToPlot.sz(dataToPlot.dims.averages)
Error in osp_iniLoadWindow (line 418)
temp = osp_plotLoad(MRSCont, gui.controls.Selected,‘ref’); %re_mm
Error in osp_onLoad (line 65)
osp_iniLoadWindow(gui);
Error while evaluating UIControl Callback.
Below is the content of the job file:

I have attached our acquisition protocol as a pdf. Please let me know if there’s anything else I could share that would help diagnose the problem.
