Is this expected? This is with r27390 on windows 10.

ReadImageInformation: Error reading C:/Users/amaga/Box Sync/PI\_Murat/grant\_proposals/Nsf\_Informatics/data\_dropbox/Chris.Percival/dont\_work.nhdr:

[nrrd] \_nrrdReadNrrdParse\_space: couldn’t parse space ““LPS””

This is the header.  
NRRD0004  
type: short  
dimension: 3  
sizes: 622 642 1085  
byteskip: 3195  
data file: ./PERCIVAL\_370.AIM  
endian: big  
encoding: raw  
space: “LPS”  
space directions: (0.02,0,0) (0,0.02,0) (0,0,0.02)

“LPS” is a valid NRRD tag. If I do something like this, it works fine:

NRRD0004  
type: short  
dimension: 3  
sizes: 622 642 1085  
byteskip: 3195  
data file: ./PERCIVAL\_370.AIM  
endian: big  
encoding: raw  
space dimension: 3  
space directions: (-0.02,0,0) (0,-0.02,0) (0,0,0.02)

Do you actually have LPS in quotation marks: `"LPS"` instead of `LPS`?  
What software was used to create this file?

Yes, LPS was in the quotes. I just used a text-editor (notepad) to generate the header. I removed the quotes and it is working now.
