Hi,
I have been subjeted to failure with seqmule as follows. Anyone know how to fix it? I would appreciate any help.

1 sample(s) in this analysis: test1
Input is exome (or captured) sequencing data.
4 variant caller(s) used: GATKLite_UnifiedGenotyper SAMtools FreeBayes Consensus
1 aligner(s) used: bwamem
Variants shared by at least 2 combinations of aligners and callers are printed.
File used for caculating coverage statistics and extracting variants: hg19_exonPlus5bp_UCSCrefGene.bed
Readgroup : READGROUP_test1
Library : LIBRARY
Sequencing platform: ILLUMINA
Reference genome build is hg19
dbsnp138 is used for variant calling and recalibration (in GATK VQSR).
Java memory usage is limited to 1750m
java executable path: java
Max number of processes: 4
NOTICE: /tmp will be used for storing temporary files

FINAL OUTPUT for test1:

NOTICE: Both consensus results and individual results are listed.
WARNING: consensus results may not be available because some variant callers or aligners may fail to generate output.
