How to use a Lambdad transform with multiple arguments ?

[Maxlo24]

Hi,
I have a list of coord on where to apply a same SpatialCrop transform on 2 3D images.
In a Compose() I wanted to use a Lambda transform to call a function that takes as arguments the 2 loaded image with the keys "Image" and "seg", the crop size and the list of roi_center coords. This function then return the 2 images cropped at one of the randomly selected roi_center.

Is it even possible to do that with Lambda or Lambdad transform ?

Thanks

It's not possible to do that with Lambda or Lambdad. I think you should create new transforms by extending monai.transforms.MapTransform

Ok, thanks
