Hi Bernat, my advice may not be that useful, but it may be better than the silence so far... Regarding the ordering of objects in hclust, if you're willing to do a bit of hacking, have a look at the stats::hclust function; you will see that the ordering is computed by a call to Fortran function hcass2. That function could be used or perhaps adapted (it uses an additional step that you will probably need to skip) to give you the ordering. If you're good at understanding Fortran code, you may even be able to re-write it directly in R. Peter

Hi, For one of our packages (CopyNumberPlots) we'll need to read 10X CNV data in H5 format. I've read in everything I need except for the cell clustering tree. It's in a format called Z format produced by SciPy hierarchical clustering. The format itself is relatively easy to parse and not so different from hclust return objects so it would be possible to create a small function to translate the Z notation into an hclust object, if needed, but I'll need to figure out the "order" vector, since it's not present in Z. - Is the Z to hclust function available in any other package? Or something equivalent to that? - If I end up transforming it by hand in a custom function, Is there a function somewhere to compute the order vector in an hclust object? Thanks Bernat
