=== Web interface ===

==== Which web browser is supported by MarsSI? ====

We do not target specific browsers, so any standard compliant 
web browser should work with MarsSI web interface.

==== Will MarsSI allow me to display/analyse data? ====

Sorry, MarsSI helps you to find and process data. There is already a lot of excellent tools or environments to work with the data, for example the team behind MarsSI works a lot with Python (+nympy, scipy, GDAL) and GIS softwares (QGIS, ArcGIS).

==== I forgot my login/password ====

Use this link: [[https://marssi.univ-lyon1.fr/MarsSI/accounts/password_reset]]

You need to have access to the email address used in the registration process.

==== I would like to change my password ====

=== Data download ===

==== Why do MarsSI need to download data? ====

MarsSI is not a full PDS mirror, we retrieve products only when
a user express interest in it to be more efficient about bandwidth
and storage.

But once a product is downloaded/processed, it will be kept!

==== Why do I need to copy data? ====

MarsSI has now a lot of products that would be hard to browse if we
just gave access to the raw directories. The "copy" action allow you
to create a subset of the data that interest you and have a cleaner
view when connecting to the SFTP server.

That being said, we are thinking of easier ways to do so in the future.

==== I requested a copy, but my SFTP directory is empty ====

You might have clicked the "Copy" button without selecting any
products in the "Data processed" pane : be sure to have selected
to copy.

==== Which SFTP client should I use? ====

Our [[SFTP|tutorial]] describe using Filezilla because we think most
people would be comfortable with it, but if you are more familiar with
another client, you can use it and just get the settings from the
documentation. 

=== Data processing ===

==== My processing failed, can I run it again? ====

MarsSI pipelines are deterministic. If some system-wide bug happens, we will restart the processing jobs, but in normal conditions it means that a failed job will result in a failed job, so job re-run are not possible.

==== DEM confidence map ====

We rely on the Ames Stereopipline software to produce our DEMs,
which do not output information such as confidence map. They stated
in the past that producing this information was really hard in their
pipeline and was not planned in the foreseeable future.

==== DEM intermediary products ====

We do not provide intermediary products such as aligned left/right
images, raw or refined correlation results. Those products use a lot
of disk space and are sometime not straightforward to open and read.
