Error when using DPABI-standardization function for single image

Dear all,

When I try to use DPABI-standardization function, I put one image for a single subject and then run the function. It appears the following error:

 Attempted to access Prctile_25_75(2,:); index out of bounds because size(Prctile_25_75)=[1,3].

Error in y_Standardization (line 86)
Median_AllSub = Prctile_25_75(2,:)';


However, when I entered multiple subjects' images, the problem solved. I am wondering whether there is anything needed to be fixed in this script?


Thank you so much!


Best wishes,

You can not do this type of standardizatoin on a single image.

Thanks Dr. Yan for replying! I am using z-standardzation (z=(x-mean(x))./std(x)). So do you mean if I use this function, I am using the images from the whole group to get the mean and standadzation deviation, rather than calculating the z score on a single subject?
