Not sure if always required

Si se ha hecho la reducción o se han seleccionado una serie de eventos previamente (ej, LiB) hay que indicarle que no hay reduction_suffix y omitir la eliminación de los dobletes (si se han eliminado manualmente, luego podrían perderse eventos interesantes).

It would be useful to introduce the ggfortify package (https://cran.r-project.org/web/packages/ggfortify/vignettes/plot_pca.html) to "cluster" all the different patients/samples (even at the subclustering step!)...in this way we can introduce a new variable that could be useful for downstream analysis!
processx is a dependency, it should be added...Thanks!

we should look at all dependencies...

Calculate the median and highlight those patients with a SD higher than X...
Maybe we can applied this method in FlowCT?? Take a look!

Add (clinical, FISH, treatment, % cells...) metadata for doing clustering... it's expected to make better clusters.
Specify different name for name it if not X11
Hi, some issues in this part.
Data should be scaled to ensure correct clustering; I added set_seed to ensure consistent results, I removed the first if loop due to errors. Now everything seems fine and working.

Collapse channel::marker to see if discrepancies or identical marker names (Irene's request).
In data.table::melt(table(mnames)) :
The melt generic in data.table has been passed a table and will attempt to redirect to the relevant reshape2 method; please note that reshape2 is deprecated, and this redirection is now deprecated as well. To continue using melt methods from reshape2 while both libraries are attached, e.g. melt.list, you can prepend the namespace like reshape2::melt(table(mnames)). In the next version, this warning will become an error.

I just modified the div.colors function by taking advantage of the colorspace package. Please look at the function and think on the possibility of replacing the old one with this one (Why the 2nd part depends upon a number >74?). Attached you'll find an UMAP with this automatically generated qualitative palette.
div.colors <- function(n, set.seed = 333){
require(RColorBrewer)
require(colorspace)
if(n < 74){
col<-qualitative_hcl(n, palette = "Dark3")
}else{
qual_col_pals = sample(brewer.pal.info)
col_vector = sample(unlist(mapply(brewer.pal, qual_col_pals$maxcolors, rownames(qual_col_pals))))
col = sample(col_vector, 333)
set.seed(set.seed); col <- sample(col, n, replace = T)
}
return(col)
}
