Trouble to generate genome indexes for human RNA-seq reads in STAR
Hi everyone, I´m a masters student and new at bioinformatics. My research is in RNA-Seq analysis, and right now I´m having trouble to generate the genome indexes prior to the alignment in STAR. A couple minutes after lauching the command line, an error message apears that the analysis was aborted by the user, a while after the message “sorting Suffix Array chunks and saving them to disk”. I´m trying to execute the command on a linux environment, through WinSCP. Apparently the parameters are correct, including the number of threads used. I don´t know where the problem might be. Any guesses?
This is the command:
/opt/STAR-2.7.9a/bin/Linux_x86_64/STAR --runThreadN 20 --runMode genomeGenerate --genomeDir /home/julia.nicoliello/genome_index --genomeFastaFiles /home/julia.nicoliello/genoma-fasta/Homo_sapiens.GRCh38.dna.primary_assembly.fa --sjdbGTFfile /home/julia.nicoliello/GRCh38.101/Homo_sapiens.GRCh38.101.chr.gtf
And these are the links to the files I´ve dowmloaded:
Thank you so much!
