Wrong size when reading noise.unsorted() #4

Closed p-sodmann closed 3 years ago

p-sodmann commented 3 years ago

Hi, when reading a file and accessing the data with sens_object.noise.unsorted() I get an array with the size of [256,30,256] The original Matlab code I am porting from, has a shape of [512, 30, 256]

The information below suggests, that there are 512 columns in the data?

twix_map_obj File: data/[...]AdjCoilSens.dat Software: vd Number of acquisitions read 256 Data size is [512, 30,128, 1, 1, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1] Squeezed data size is [256,30,128,2] (['Col', 'Cha', 'Lin', 'Ave']) NCol = 512 NCha = 30 NLin = 128 NAve = 2

Hi @p-sodmann,

Try setting sens_object.noise.flagRemoveOS = False for the time being. However, this flag should be reflected in the description of the data in a more obvious way and perhaps the default setting should be different.

Hi,

this helped. The Flag was not raised in MatLab by default for some reason.

Thank you for maintaining this python port!
