Dear Bioconductor Community,

The last version of the package (HOPACH) generates a wrong output, e.g. using the R code from http://127.0.0.1:14749/library/hopach/html/makeoutput.html

I have received output (please below) from which it is clear that some items clustered to Cluster0 have a much higher cluster membership probability to be in Cluster1 or in Cluster2. From my previous experience, it never happened before in hopach outputs.

Any ideas?

Thanks

Alex

Can you provide a more reproducible example, perhaps with some simulated data or a subset of your actual data? The following seems to produce consistent results

> example(makeoutput)
...
> res = read.delim("HOPACH.out", sep="\t")
> apply(res[,grep("Membership", names(res))], 1, which.max) - 1
 [1] 1 0 2 0 0 3 3 0 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
> res$Cluster.Number
 [1] 1 0 2 0 0 3 3 0 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2

Yes, I can provide my actual data as input for hopach. Its size is 1MB only. What is best way to send it?

I applied your code to my data and it doesn't produce a consistent result:

res1 = read.delim("conditions.dm.cos.hopach.out", sep="\t")
> dim(res1)
[1] 85 13

> apply(res1[,grep("Membership", names(res1))], 1, which.max) - 1
[1] 4 4 3 3 0 0 4 4 4 3 3 0 3 4 2 3 1 3 3 3 3 3 3 3 3 3 3 4 4 4 4 3 0 4 3 3 4 0 4 3 4 4 4 4 4 4 4 0 3 3 3 4 0 0 3 2 0 4 4 2 2 3 4 4 3 4 4 4 4 4 3 3 3 3 4 4 0 4 3 3 3 3 3 3 3
> res1$Cluster.Number
