output images from two-tail test of one-way t-tests (matlab_TFCE) #7

Hello,

I have a question regarding the image output when using the function "matlab_TFCE" with analysis "oneway". As I understand from the documentation, there should be two images as output (one for the negative tail and one for the positive tail): % If tails == 2, two such output images will be returned, one for the % 'positive' tail and one for the 'negative' tail of the test, % respectively. However, when I run the function, only one output image is produced. Can you help me with this? Thank you very much.

Hi Georgette,

For the 'onesample' analysis option, you should indeed get two output images, as the documentation describes. Are you using the following syntax?

[pcorr_pos,pcorr_neg] = matlab_tfce(analysis,2,imgs,imgs2,covariate,nperm,H,E,C,dh,parworkers,nuisance)

It's important to "catch" both outputs with the "[pcorr_pos,pcorr_neg] =" bit of the code. The output to a single variable seems like the likely reason you might be experiencing this issue.

Best, Mark
