The Hera Interface

After logging into Web Hera, the interface will launch in your web browser. The interface and some useful information about it is shown in Figure 1. There are four different sections or windows. The User Account Window, Tool Parameter Window, and Command Window may be resized relative to each other by clicking and dragging their horizontal borders. The Available Tools Window is on the left hand side of the interface. Tools are grouped by subheadings of Ftools and mission-specificity.

Files may be uploaded to your Hera account, but directories cannot.

Figure 1: The Hera interface. The different window sections are labeled in blue and user interface buttons are labeled in red.

The user interface buttons provide ways to navigate, and modify and view files. Hovering them will produce a description of the button's function. Double-clicking on a folder's name will open it. In Figure 2, a file list is shown in the User Account Window. Icons to the right of each file indicate display options, as well as download, rename, and delete options. Please note that files in an account are actually links until they are acted upon, by, for example, clicking the "Replace Link" icon. The names of these "link files" are red. When a link file has been replaced with a copy from the server, its name is shown in blue.

It is likely that the first thing you will want to do is uncompress your data. To unzip a file, highlight it and click on the Replace Link icon, so the file will be copied into your account from the server. When the file has been copied over, the "Unzip" icon will appear and can be selected. The box will disappear when the data is uncompressed. Please note that multiple files can be selected at once by highlighting with the shift key (for a continuous block of files) and the control key (for particular files).

To use the Parameter Window, either double-click on a task in the Available Tool Window or type in the name of the task and click "Get". The task's parameters will be listed in the Parameter Window and you can edit them as needed. To run a task, just click on the "Run (task name)" button at the top or bottom of the Parameter Window.

You can also run tasks in the Command Window by typing in the task name and any parameters you need, as you would if running SAS on the command line on your local machine.

Either way, feedback such as server communications, warnings, and errors will be displayed in the Command Window. Please remember that the Command Window cannot be used to navigate or manage your account; if you want to change directories, make a new directory, change file names, delete files, etc., this can only be done through the interface buttons in the User Account Window. As with locally-run SAS, the output from tasks will be placed in the directory in which that task was called.

Tasks may be canceled, regardless of where they were called, in the Command Window by clicking on the "Restart" button. (It only appears when a task is running; look for it on the right hand side of the Command Window.)
