I was running STAR on my local computer with i5 8 generation processor and 8 gigs of RAM. I was implementing a variant calling pipeline on simulated data of the ebola virus. I started with forward reads (.fq) and reverse reads (.fq) along with the reference genome of ebola(.fasta). I successfully used GATK to make reference genome index. While I was doing alignment with STAR (STAR --genomeDir ../genomedir/ --readFilesIn ../ebola_mut_reads1.fq ../ebola_mut_reads2.fq --runThreadN 4), I encountered an error.
Error is as follows
Dec 17 15:00:05 ..... started STAR run
Dec 17 15:00:05 ..... loading genome
Dec 17 15:00:06 ..... started mapping
