Hello, I am defining some tools for my own galaxy installation and I would like to know if there is a more elegant solution for redirecting error output than the one in the next config file: <tool id="gatk_mio" name="calling with gatk"> <description>calling with gatk</description> <command> ln -s "${input}" input.bam ; samtools index input.bam; java -jar /home/ralonso/software/GenomeAnalysisTK-3.3-0/GenomeAnalysisTK.jar -T UnifiedGenotyper -R /home/ralonso/BiB/Galaxy/data/Cclementina_v1.0_scaffolds.fa -I input.bam -o $output *2>/dev/null;* </command> <inputs> <param format="bam" name="input" type="data" label="bam"/> </inputs> <outputs> <data format="vcf" name="output" /> </outputs> <help> bwa </help> </tool> Best regards many thanks -- Roberto Alonso Functional Genomics Unit Bioinformatics and Genomics Department Prince Felipe Research Center (CIPF) C./Eduardo Primo Yúfera (Científic), nº 3 (junto Oceanografico) 46012 Valencia, Spain Tel: +34 963289680 Ext. 1021 Fax: +34 963289574 E-Mail: ralonso@cipf.es
