Dear John, BioC-community, I tried to run the runBioHMM function on my data (Nimblegen HD 2.1 Arrays), however I am always getting the error: "Error: segfault from C stack overflow". What is the reason for that error? Are the data too big? I tried to split the array according the chromosomes but it did not help. Only after splitting the data into small pieces the function run successfully. I preprocessed the data according the snapCGH manual (snapCGHguide.pdf), below is the code that produced the error, object class and sessionInfo.

You need to provide us with more information so that we can help you. A good start would include: - sessionInfo() - the exact code you are running - more details on the input data. > > What is the reason for that error? Are the data too big?

That does suggest that data size is the issue. Are you able to obtain any details on where the segfault occurs? R-devel includes a fix for an issue in gsub that could cause a stack overflow segfault for long strings. You might try installing latest R-devel, Bioconductor devel packages and see if the problem is reproducible there. > > I preprocessed the data according the snapCGH manual (snapCGHguide.pdf), > below is the code that produced the error, object class and sessionInfo. > Maybe you forgot to copy/paste? + seth _______________________________________________ Bioconductor mailing list Bioconductor at stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/bioconductor Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor -- Robert Ivanek Postdoctoral Fellow Schuebeler Group Friedrich Miescher Institute Maulbeerstrasse 66 4058 Basel / Switzerland Office phone: +41 61 697 6100

Can you make your MA.cgh2 object available (you could use a service like http://drop.io/) to share an rda file created using save(MA.cgh2, file="MA.cgh2.rda", compress=TRUE). If you send me a URL in private mail, I will see if I can reproduce the issue and investigate further. + seth -- Seth Falcon Bioconductor Core Team | FHCRC

A brief update: Robert made a version of the data available and the error is reproducible and seems to be coming from code within the snapCGH package. The package's maintainer has been notified off-list with some additional debugging details. + seth -- Seth Falcon Bioconductor Core Team | FHCRC
