Hi Matthew,

Thanks for your email.

Could you please give more information how to do this.

I a new FSL user and I am mainly using the FSL interface.

Not very familiar to work from the command line.

Any further detail how to do this would be highly appreciated.

Thanks a lot,

Gina

Hello Gina,

You can use fslcreatehd to create a 3D reference of the desired dimensions and use that along with the -applyxfm -init options ( passing an identity matrix to the -init option ) to resample in a more flexible manner.

Hope this helps,

Kind Regards

Matthew

Hi there,

I have 4D data with dimensions [516, 516, 75, 99]. I would like to downsample my image to [128, 128, 75, 99], i.e. downsample x- and y-dimensions only.

I tried the flirt tool using -applyisoxfm but it downsampled x, y and z directions.

Does anyone know how to downsampled only x- and y-?

Thanks a lot,
Gina
