Hi Anjali,

For some reason your values of 1-6 are actually multiplied by 256.
So your dataset contains values of 0, 256, 512, ..., 1536. I'm not
sure how that would happen without you explicitly asking for it.
Some possibilities:

- You drew values of 1-6, but you or someone else used an external
program to multiply all values by 256. If you had done it with 3dcalc,
it would be part of the history.

- Multiples of 256 were intentionally drawn by someone.

- There is some bug in afni that did this (though we should hear about
this from other people, too).

Each of these seems somewhat unlikely from what you have said.
But just from the dataset, these are my best guesses.

Were you the one that created these?
