Dear hcp-Experts,
I tried to find if there are significant differences in the myelination in
two groups of subjects using PALM. Therefore after processing files I've
merged them using wb_command -cifti-merge
File looks like this:
wb_command -file-information output_32k_myelin.dscalar.nii
Name: output_32k_myelin.dscalar.nii
Type: Connectivity - Dense Scalar
Structure: CortexLeft CortexRight
Data Size: 1.43 Megabytes
Maps to Surface: true
Maps to Volume: false
Maps with LabelTable: false
Maps with Palette: true
All Map Palettes Equal: true
Map Interval Units: NIFTI_UNITS_UNKNOWN
*Number of Maps: 6Number of Rows: 59412*
Number of Columns: 6
Volume Dim[0]: 0
Volume Dim[1]: 0
Volume Dim[2]: 0
Palette Type: Map (Unique for each map)
*CIFTI Dim[0]: 6CIFTI Dim[1]: 59412*
ALONG_ROW map type: SCALARS
ALONG_COLUMN map type: BRAIN_MODELS
Has Volume Data: false
CortexLeft: 29696 out of 32492 vertices
CortexRight: 29716 out of 32492 vertices
But when i run it with palm i get following error:
Reading input 1/1: output_32k_myelin.dscalar.nii
Reading design matrix and contrasts.
error: The number of rows in the design matrix does
not match the number of observations in the data.
*- Rows in the matrix: 6- Observations in the data: 59412*
So my question is there a way to make palm see that subjects are in CIFTI
Dim[0] rather than 1. Alternatively is there any other way to assess
differences?
*wb_command. Version: 1.1.1palm. Version: alpha83*
Thank you for your answers in advance.
宜しくお願い致します。
Sincerely,
