Disk space error while aligning reads using STAR Hi am trying to align RNA-seq reads using STAR through following commands,

STAR --runMode alignReads --runThreadN 26  --outSAMtype BAM  SortedByCoordinate Unsorted --sjdbOverhang 100  --genomeDir wheat --readFilesIn G3_cleaned_R1.fastq G3_cleaned_R2.fastq --sjdbGTFtagExonParentTranscript wheat.gff3

How this problem can be solved?
STAR versions 2.6.0b and 2.6.0a are unstable,  as written Issues performing variant calling with GATK you are using version 2.6.0b. You should switch to version 2.6.0c which is stable.  Also avoid to perform multiple alignments in the same directory.
