rsubread exactsnp ERROR "memory not mapped"
Hi All,
I am trying to call SNPs from RNAseq data. I am using exactSNP function from Rsubread package.
I got an error ( * caught segfault * address (nil), cause 'memory not mapped')
The script is as follows;
library(Rsubread)
exactSNP(SNPAnnotationFile="All_20151104.vcf.gz",readFile="PB01_1_sv.sam",isBAM=FALSE,refGenomeFile="BSgenome.Hsapiens.NCBI.GRCh38.fasta",outputFile="PB01_1_sv.sam.vcf",nthreads=8)
*** caught segfault ***
address (nil), cause 'memory not mapped'
Traceback:
1: .C("R_SNPcalling_wrapper", as.integer(n), as.character(cmd), PACKAGE = "Rsubread")
2: exactSNP(SNPAnnotationFile = "All_20151104.vcf.gz", readFile = "PB01_1_sv.sam", isBAM = FALSE, refGenomeFile = "BSgenome.Hsapiens.NCBI.GRCh38.fasta", outputFile = "PB01_1_sv.sam.vcf", nthreads = 8)
aborting ...
Thanks,
Tarek

With memory errors the first thing to suspect is that you don't have enough available. Have you tried to run this with a smaller number of threads (instead of 8 above)?
Hi, No I have not, but I am using the university server and I know that these threads are available. Thanks Tarek
Hi, I tried it with only 2, and I got the same error
Are you allocating a specific amount of memory for the job (is there a default value, especially if you are using a job scheduler)?
