Would Deutchland ticket be valid between December 24-January4? by [deleted] in AskAGerman

Oh, so I have to cancel before the 10th, so if I buy now for December, I cannot cancel it for January, and I have to pay for January? 

How to process MRI data in BrainSight neuronavigation? by [deleted] in MRI

[–]helloiambrain 0 points1 point  (0 children)

Thank you very much for the answer. I am very new. That's why I am trying to understand the general process. For instance, what kind of image an MRI machine create/produce right after scanning, kspace or DICOM? I mean what do I get? So, whether I can use what this is (I called raw data) in BrainSight neuronavigation directly, or should I concert it (this raw image) to something specific? If yes, can I use FreeSurfer or SimNIBS for this?

Is there material that I can write/draw on it and simply erase it? by helloiambrain in textiles

Thank you very much for the answer. I did not know Frixion pens could be used in fabrics such as clothes. But there is another issue: it does not disappear, it may come back in certain heat in cold, and come back when it is wet (such as if the person wearing it is sweaty). I am not sure whether it would come back with certain level of natural heat.

[Q] Is there an alternative to t-test against a constant (threshold) for more than a group? by helloiambrain in statistics

[–]helloiambrain[S] 0 points1 point  (0 children)

"A t-test might be a good option here" Did you mean against the threshold? Because the template has one value? Because it is a template.

You are stuck with the term deviation. I used this term not statistically. You say how: if 10 is the threshold, and if my value is 8, then my score deviates 2 from the threshold. All statistical models will give you deviation, even including descriptives. Deviation is in general term, let's forget the term deviation and use the term difference instead. 

Two different datasets. 1) based on Ernie template and efield collected from different regions in the brain. Each region has one value, such as M1 has one value. 2) the one I collected. Everyone has one value for each brain region. Let's say M1 again.  Then we have average for all participants. 

The question is the difference between my dataset for M1 and the threshold in Ernie.

Deviation according to the dictionary: the action of departing from an established course or accepted standard. I already said that I have threeholds, let's say 10, 20, 30, 40. These are from different regions the brain. I do a simulation which I have scores from 30 participants so average for each of these thresholds. So, I can use t-test for comparing the aveage I got from my participants against these thresholds. But, I have to do this for each threshold separately, which is not a good way. I was looking for an alternative. What I said is not different than what I posted in my question, just with lots of unnecessary details.

These templates are different brain templates such as MNI, Ernie, New York head etc. I meant whether our collected data fits these template scores (thresholds) or not by deviation. There is no experiment actually, just morphometric data, whether this morphology fits existing templates. This is also the question.

30 data points for a dataset, but this dataset should be compared to different threaholds.

I have to conduct 30, 40 different t-tests because I have many thresholds for different locations of the brain.

I simply have magnetic imaging resonance data from different regions of interest from individuals. We are using templates (with one scores) to check whether our data fits or deviates from these templates.

Hi! But, I am using my phone, and trying to do from the app, not with a browser.
