While running my snakemake file in cluster I keep getting an error,

```
snakemake -j 20 --cluster "qsub -o out.txt -e err.txt -q debug" -s 
seadragon/scripts/viral_hisat.snake --config json="<input file>" 
output="<output file>"

```

Now this gives me the follwing error, 

```
Error in job run_salmon while creating output file 
/gpfs/home/user/seadragon/output/quant_v2_4/test.
ClusterJobException in line 58 of seadragon/scripts/viral_hisat.snake
:
Error executing rule run_salmon on cluster (jobid: 1, external: 156618.sn-mgmt.cm.cluster, jobscript: /gpfs/home/user/.snakemake/tmp.j9nb0hyo/snakejob.run_salmon.1.sh). For detailed error see the cluster log.
Will exit after finishing currently running jobs.
Exiting because a job execution failed. Look above for error message

```

Now I don't find any way to track the error, since my cluster does not give me an way to store the log files, on the other hand `/gpfs/home/user/.snakemake/tmp.j9nb0hyo/snakejob.run_salmon.1.sh` file is deleted immediately after finishing. 
Please let me know if there is an way to keep this shell file even if the snakemake fails.
