-====== Create a sample for a person ======
-A sample is a compressed file of the .tgz (.tar.gzip) format, containing a number of metaphase images from the person. It is the basic unit for estimating the radiation dose that the person is exposed to. To create a sample, click the ‘New sample’ menu item within the ‘Sample sets’ menu.
-===== Prepare =====
-{{ file:bgq:create_a_sample_prepare.png?nolink }}
-First, you need to upload the metaphase images of the person to the BGQ server, which can be accomplished by the bottom region of the right panel. In this region, the left part displays the contents on the disk drives of the local computer you are using; the right part displays the contents on the BGQ server. In the left part, select the metaphase images or the directory containing them; in the right part, select the destination directory on the BGQ server. Then click the ‘Upload’ button in the middle. If the upload takes some time, a progress dialog will pop up. It displays the current uploading percentage in a progress bar and the name of the file being uploaded.
-In the right part, you can also create a new directory, rename a directory/file and delete a directory/file on the BGQ server by right-clicking on the item. You can upload multiple files and directories at one time. The metaphase images of each person should be uploaded to a separate destination directory; for example, Persons ‘S01’ and ‘S02’ will correspond to two directories on the BGQ server named ‘S01’ and ‘S02’. And the directory should only contain the images.
-After uploading the metaphase images, you can create samples with the top region of the right panel.  You can create multiple samples at one time. Click the ‘Select’ button within the row containing the ‘Source’ label. In the directory chooser that pops up, select one or more directories to which the images were uploaded on the BGQ server, and click the ‘OK’ button.
-Then the paths of all selected directories will be displayed in the drop-down list. For the source directory currently being displayed in the drop-down list, the other components in the top region of the right panel provide the following associated information:
-  * ‘Name’ text field: the name of the newly created sample. It is prepopulated with the name of the directory.
-  * ‘Description’ text area: providing a number of description entries for the sample. It is prepopulated with common entries, including ‘Coordinate of the person’ and ‘Exposed physical dose’. You can add or remove any description entry.
-  * ‘Apply to all’ checkbox: If checked, the current content in the ‘Description’ text area will be applied to all samples; in other words, all samples will have the same descriptions.
-  * ‘Metaphase images included’ list: It is automatically populated with the names of all *.tif images in the directory and the image count.
-You can select another directory in the drop-down list, then the ‘Name’ text field, ‘Description’ text area and ‘Metaphase images included’ list will be updated accordingly. After you finish editing ‘Name’ or ‘Description’ for one sample, its content will be automatically saved. You can also click the ‘Clear’ button to clear the contents in all of the components. Each sample must have a name, but may not have any description.
