External Email - Use Caution
Hi,
I apologize for the repeated emails, but I was wondering if you had the time to look at the 1mm data.
Sorry again and thank you so much, Samuel

That's so weird. Can you make the data available to us?

External Email - Use CautionHi Dough,
Thanks for your response. We followed your suggestion and ran the 7T data without the -highres option. This gave us values which are in the normal range of what we get when using 3T mean curvature data. We looked whether there was a fixed scaling factor between the data with and without the -highres option. This did not seem to be the case as the scaling factor for the different subregions varied between 1,18 (for the left G_subcallosal) and 2,95 (for the left S_collat_transv_ant). I attached a pdf with the results.
Thank you again

This does not make sense to me. What resolution is your 3T and 7T data? Can you run the 7T data at 1mm (ie, without the -hires option) and see if it changes?

External Email - Use CautionHello,
We are looking at some of our data acquired on a 7T magnet. We ran recon-all with the “highres” flag. The obtained results for cortical thickness and cortical volume are very comparable to data that we obtain when using 3 T brain images. However, the results for cortical curvature are significantly different from what we get by our 3 T data. I attach the output of mean cortical curvature values using the Destrieux atlas for a 3T and 7T dataset on healthy controls. As you can notice, they differ roughly by a factor of 2. Any explanation for what may cause this large difference?
Thanks,
Samuel
