EMBL-EBI EMBOSS pepwindow Python Client:

Sequence statistics and plots with pepwindow.

[Required (for job submission)]
  --email               E-mail address.
  --sequence            The sequence to be analysed can be entered directly into
                        this form. The sequence can be in GCG, FASTA, PIR, NBRF,
                        PHYLIP or UniProtKB/Swiss-Prot format. Partially formatted
                        sequences are not accepted.

[Optional]
  --windowsize          Window size for averaging (smoothing) the hydropathy plot.
                        Use an integer between 1 and 200.
  --normalize           Normalize data values (mean = 0.0, standard deviation = 1.0).

[General]
  -h, --help            Show this help message and exit.
  --asyncjob            Forces to make an asynchronous query.
  --title               Title for job.
  --status              Get job status.
  --resultTypes         Get available result types for job.
  --polljob             Poll for the status of a job.
  --pollFreq            Poll frequency in seconds (default 3s).
  --jobid               JobId that was returned when an asynchronous job was submitted.
  --outfile             File name for results (default is JobId; for STDOUT).
  --outformat           Result format(s) to retrieve. It accepts comma-separated values.
  --params              List input parameters.
  --paramDetail         Display details for input parameter.
  --verbose             Increase output.
  --version             Prints out the version of the Client and exit.
  --quiet               Decrease output.
  --baseUrl             Base URL. Defaults to:
                        https://www.ebi.ac.uk/Tools/services/rest/emboss_pepwindow

Synchronous job:
  The results/errors are returned as soon as the job is finished.
  Usage: python emboss_pepwindow.py --email <your@email.com> [options...] <SeqFile|SeqID(s)>
  Returns: results as an attachment

Asynchronous job:
  Use this if you want to retrieve the results at a later time. The results
  are stored for up to 24 hours.
  Usage: python emboss_pepwindow.py --asyncjob --email <your@email.com> [options...] <SeqFile|SeqID(s)>
  Returns: jobid

Check status of Asynchronous job:
  Usage: python emboss_pepwindow.py --status --jobid <jobId>

Retrieve job data:
  Use the jobid to query for the status of the job. If the job is finished,
  it also returns the results/errors.
  Usage: python emboss_pepwindow.py --polljob --jobid <jobId> [--outfile string]
  Returns: string indicating the status of the job and if applicable, results
  as an attachment.
