Starting Sentira for the first time
TThe first time you start Sentira you will be asked to accept the End -User License Agreement (EULA) which you can also read here. You will also be shown the License Manager which automatically starts when you are using a trial license or your license has expired. Your trial license will last for 30 days and you can use Sentira without any limitations during this period.
Activating your license key
If you have purchased a license key then when the License Manager appears you can copy and paste your new key in to activate it. Copy the license id into the License ID field and enter the password. Click the Activate button and after a second or two you should see a message indicating that this was successful and the Current Status will update accordingly.
Loading your data into Sentira
To start creating visualisations you need to open a file containing some data. Sentira enables you to import data from a variety of different file formats including:
- *.skd – Sentira files
- *.csv – Comma separated variable (CSV) file
- *.smi – SMILES file
- *.sd and *.sdf – MDL SD file
- *.mol – MDL Mol file
- *.txt – Text file
- *.* - Any file which contains text delimited by tabs, spaces, commas, colons or semicolons
Select Open from the File menu, chose an appropriate file and click the Open button. If you have selected a text file then a preview will be shown enabling you to confirm the delimiters used, otherwise you will see your file displayed as a data set. Note: For text files of type *.csv or *.txt the first row is used as a header row.
When a text file is opened Sentira will attempt to determine the type of data in each column. Where the values within a column are predominantly numerical Sentira will treat the data as numbers. If the numbers have modifiers then these will also be recognised (the following modifiers are accepted: >, <, >=, <=). If Sentira finds a column that contains text values that are repetitive then it will treat these values as categorical data. Any text values that appear to be SMILES strings will be treated as molecules. Sentira will also look for text that appears to be dates, with the following formats recognised:
- 12 22 2001
- Dec 22 01
- December 22 01
- 2001 Dec 01
- 2001 December 01
- 2001 12 01
All other data are treated as text. If Sentira has incorrectly determined the type of data in a column then you can edit this (see XXX).
Selecting the Data to plot
There are two ways to create plots within Sentira. One way is to select a plot type from the buttons on the right-hand toolbar, after which you can then choose which properties to show on each axis. Alternatively, if you select the property columns in the data set that you would like to include within a plot, an appropriate plot will be created which shows those columns. Depending upon the number, and type, of columns that you have selected an appropriate plot type will be chosen for you. However, if you would like to see a different plot for these properties you can simply change the plot type by using the plot buttons on the right-hand toolbar.
If you have opened or created more than one data set, you can also include the data from those other data sets in the plot you have created. All the data sets will be listed in the key below the plot. Those which contain the properties that are displayed in the plot will be enabled and simply checking the box next to the name of the data set you would like to include will add it to the plot. The up and down arrows next to the key control the order in which points from the different data sets are layered within the plot. You can control whether a data set is on top by selecting its name in the key and clicking the up or down arrows to change its position.
