Ok, thank you Denis.

Hi Denis, yes, it is a 3D fusion texture done with anatomist 3.0.0, implying a mesh at the format *.tri and an analyze format 3D image. I tried with another SPM T-map and this rescaling happened again, with another translation value. I can send you the mesh and a T-map if you want to try with my dat...

Hi Olivier, thank you for your answer. Actually, the final texture is not rescaled between 0 and 1: For instance, I start from 3D data between [-3.2;+3.14] and the saved texture values are between 20.29 and 26.61, so there is at least a strange translation (and apparently not here but perhaps someti...

When I load an exported texture file (*.tex), the values are not in the original range anymore.
Do you know what is going on and how to prevent this automatic rescaling?

Thank you very much,
Nicolas.

Thank you Denis, your solution works fine.
Nicolas.

Hi, Starting from a mesh file with n different time steps (for instance n=2 with a "normal" and inflated mesh) and a 3D activation map, one can do a 3D fusion to overlay activations on the mesh. However, the data projection on the mesh is re-computed when I use the time slider. In previous...

Ok, thank you very much.

Ok, thank you for your answer Yann.

I have already tried the *.trm conversion, but could not successfully apply it to reslice my image...

I answer my own post ;-) I should actually not apply this .mat file before the tensor estimation, as the diffusion directions are linked to the image without applying the .mat. I nonetheless face a new problem now, losing the coregistration between the diffusion images after the processings in Brain...

Right. But still, the "original" data I get from the Bruker 3T scanner from La Timone, Marseille, have an associated .mat file (like SPM-processed images indeed). How can I apply this transformation properly (minimizing interpolations) to get rid of it for further processings within Brainv...

Excuse me, I was not clear.
It is *.mat associated with the *.hdr and *.img files (Analyze format).

Hi, sorry, having a closer look at what's available, I could answer my question 2) from previous post: Olivier's Brucker importation python script squares the images while importing them. But it lead me to another problem: the .mat files information attached to the diffusion weighted images seems lo...

Hello DTI-ers! I face exactly the same problem of non-squared DT and T2 images when trying to use the DTI distorsions correction, and therefore have 2 related questions: - Cyril, is the new release you are talking about ready? (I have the Linux BrainVISA 3.0.0 version, but it seems to me the distors...

Dear Brainvisa experts, I have a few questions regarding the computation of cortical segmentation and surfaces extraction in the AnaDoALotOfThings Pipeline: - I understand the GM/WM interface detection method from your 1995 JMIV paper, allowing a spherical topology constrained interface detection. W...

Hi, I had the following problem while trying to export GIS images obtained during the anatomical segmentation process to the analyze format. I start with anat.img/hdr (Analyze format) in the pipeline "Prepare subject...", which is a 1x1x1mm resampled version of the original anatomical imag...
