Dear Kolluri,

Would MultiStackReg (http://bradbusse.net/downloads.html) solve the problem?

Best wishes

Subject: Stackreg zero padding issue

 Hi,
I raised a similar question on image.sc forums
https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fforum.image.sc%2Ft%2Fstackreg-zero-padding%2F35129&amp;data=02%7C01%7Ckrs5%40leicester.ac.uk%7C831e301fc84c445082c808d7cb084732%7Caebecd6a31d44b0195ce8274afe853d9%7C0%7C1%7C637201108733821008&amp;sdata=Aqe5bVuIUzt1oXRLH4UgHgU4iQS1RvSd7m%2BXOn7v%2FzY%3D&amp;reserved=0

We use Stackreg to align an image stack and try to apply the transformation matrices obtained to another channel of the same image stack. We do rigid registration of the image stack and stackreg does great. However, it also does zero padding of some of the images in the stack. Now, when we apply the transformation matrices (localTransform) obtained from StackReg to another channel of the same stack, this zero padding does not happen and so although the transformation matrices are applied, the 2 image stacks are not aligned well.

Any idea how to resolve this issue?

Thanks
