Hello,
Wim is probably better placed to answer this, but it looks to me like
there is a restriction in the Bruker parsing code to <= 3D. (Probably we
didn't have any 4D data set to test this on.) So if you look in the file
ccpnmr2.0/python/ccp/format/bruker/processingParsIO.py, around line 133
you will see:
self.numDim = 1
for i in range(3,1,-1):
if ('proc%ds' % i) in files:
self.numDim = i
break
Change that 3 in the second line to 4 and see if that works. (So, is
there a proc4s file for 4D data sets?) (Even if that works, it's possible
there will be another issue downstream.)
