[Chau, Reina]

Thank you both! I will look thru the links and see if I can implement a fix.

Best,

Reina C.

Hi Reina,

Note that CaDrA results on Mac ARM64 are also affected:
https://bioconductor.org/checkResults/devel/bioc-mac-arm64-LATEST/CaDrA/

See Martin Grigorov's blog post here
https://blog.bioconductor.org/posts/2023-06-09-debug-linux-arm64-on-docker/
for how to debug Linux ARM64 related issues on a x86_64 host.

Note that different architectures use slightly different floating point
arithmetic with slightly different precision. This can affect the
results of your numerical calculations. The degree to which they are
affected will vary greatly depending on what calculations you perform
and how you perform them. So it's important to implement things in a way
that tries to minimize the impact of these variations as much as possible.

See https://go.dev/ref/spec#Floating_point_operators for some further explanation of the problem and possible fix by explicit rounding (in Golang, but I guess something similar happens in R)


Best,

H.
