+Batch times series Analysis
+===========================
+
+The `batch_timeseries` tool can take an `analysis_compare` input yaml file,
+and instead of running the time series analysis for each job on
+the interactive shell terminal in series, it uses slurm to submit
+each job as an independent job. 
+
+On jasmin, users can run up to five jobs simulataneously,
+so this can singnificantly boost the speed of the analysis. 
+
+The command to run it is:
+```
+batch_timeseries - y comparison_recipe.yml
+```
+
+There is also an optional flag `-d` or `--dry_run` to test the batch_timeseries,
+which outputs the submission command to screen but does not submit the jobs.
+
+Note that this task does not run the `analysis_compare` suite so it will 
+not generate the html report. However, the html report can be generated more quickly
+with the `-s` skip the `analysis_timeseries` section 
+described above. 
+
+In addition, note that this will not run the `download_from_mass`
+script, so jobs added here will not be included in the automated download.
+However, these jobs are added for automated download when `analysis_compare` 
+is used.
