--- # Data: Getting data into Galaxy .footnote[Tip: press `P` to view the presenter notes] ??? Presenter notes contain extra information which might be useful if you intend to use these slides for teaching. Press `P` again to switch presenter notes off --- ### <i class="fa fa-question-circle" aria-hidden="true"></i><span class="visually-hidden">question</span> Questions --- # Getting data into Galaxy ??? -> Pressing **P** will toggle presenter mode. --- # Many ways to get data into your workspace - Import from your computer - Import from a URL - Directly enter text - Import using FTP - Import from *defined* data sources - Import from *undefined* data sources - Import from a Galaxy Data Library ??? - To do analysis in Galaxy you first need data to work on. - There are many ways and sources for getting data into your history. - Which method you use depends on where your data is, and how big it is - This tutorial will cover all of the techniques listed here. --- # The Get Data toolbox section .pull-right[![Click on Get Data to expand it](../../images/get_data_boxed.png)] - *Click* on the **Get Data** toolbox in the toolbox (the left panel) --- .pull-right[![A typical list of data sources](../../images/get_data_expanded.png)] # The Get Data toolbox section - Expands to show data sources that have been *defined* on your server - The specific data sources available on your Galaxy instance are determine by the server's administrator - All of these data sources can bring datasets (files) into your Galaxy workspace ??? This shows the list of data sources that were available on usegalaxy.org in mid 2017. --- ### **Upload File** data source ![Click on Upload File to show the import data form](../../images/upload_file_toolbox_entry.png) or .image-25[![click on upload button](../../images/upload_button.png)] ??? Two ways to launch the upload file form. --- # Upload files from your computer ![Upload file form](../../images/upload_file_form_empty.png) ??? - The **Upload File** data source can import data: - from your computer - using a URL - by directly entering text - and via FTP This is probably the most commonly used tool for bringing data into Galaxy, and it is installed on almost every Galaxy server. --- # Upload files from your computer ![Options for importing files from your laptop](../../images/upload_file_form_empty_local_choices.png) ??? - Drag and drop is supported - as is the standard file selection using your browser. --- After dragging and dropping / choosing* local files: !(../../images/upload_file_file_list.png) ( * but before importing ) ??? - Here we have imported 13 files - one with genome annotation in GTF format - 12 paired end read files from an RNA-Seq experiment* - could import them now and have Galaxy guess at their file types. * From UC Davis Training Material. --- Could rely on Galaxy to set datatypes for imported datasets, but sometimes it guesses wrong. Galaxy can't guess the build (genome assembly), so this needs to be manually set ![Set datatype for all imported datasets](../../images/upload_file_set_all_datatype.png) --- But now we need to fix the datatype of the first imported dataset, because it has a different datatype: ![Manually set datatype for one dataset](../../images/upload_file_set_individual_file_type.png) Can also set the build (genome assembly) for individual files. ??? - Here we are manually setting the first dataset's datatype to GTF, a common genome annotation format. --- Once you have set everything, start the upload process: ![Ready to upload files. Click on start](../../images/upload_file_ready.png) ??? - Data transfer does not start until you click Start. --- You can then close the form ![Ready to upload files. Click on start](../../images/upload_file_in_progress.png) ??? --- All the items will appear in your history ![Files are loaded into your current history.](../../images/files_uploaded_into_history.png) and are ready to use when green. --- ## Directly enter text Sometimes it's useful to enter values directly. This only works if your dataset is tiny. ![Select Paste/Fetch data](../../images/upload_file_form_empty_paste.png) --- ## Directly enter text Enter the data by typing (or pasting) it in the input box: ![Select Paste/Fetch data](../../images/upload_paste_direct.png) You can also set the datatype and build. *Click* **Start**, and then **Close**, and the new item shows up as **Pasted Entry** in your history. --- # Import using FTP --- ### Why use FTP? - Older Galaxies did not support uploading files larger than 2GB in size - Many people are very comfortable using FTP to upload large datasets and you can sometimes resume interrupted uploads. --- ### How to use FTP - The Galaxy server's administrator must have [enabled FTP](https://galaxyproject.org/admin/config/upload-via-ftp/) on the server - You will need to create an account on that Galaxy Server - You will need to install FTP software, or to run FTP from the shell See https://galaxyproject.org/ftp-upload/ --- ## Step 1: Create an account on the Galaxy server - To use FTP, you'll need to have an account on the Galaxy server you are using - See the *Creating an account on Galaxy* tutorial --- ## Step 2: Make sure you have FTP software: FileZilla .pull-right[.image-25[![FileZilla](../../images/FileZilla_logo.png)]] - [FileZilla](https://filezilla-project.org/) is a free FTP client that is available on [Windows](https://filezilla-project.org/download.php?platform=win64), [MacOS](https://filezilla-project.org/download.php?platform=osx), and [Linux](https://filezilla-project.org/download.php?platform=linux) - There are many other options - If you don't already have an FTP client, download and install FileZilla. --- ## Step 3: Establish FTP connection to your Galaxy server - Run your FTP client (FileZilla in these slides) and establish a connection to the Galaxy server you are using (usegalaxy.org in this example) - Provide - the instance's FTP server name (e.g. usegalaxy.org) - your full username (usually an email address) and password ![FTP Connection Params](../../images/ftp_client_connect.png) --- ![Successfully connect](../../images/ftp_client_connected.png) Successfully connected --- ![Navigate to the files you want to transfer](../../images/ftp_client_upload.png) Right click on the files and upload them. --- ![FTP transfer in progress](../../images/ftp_client_transferring.png) FTP Transfer in progress... --- ![FTP transfer complete](../../images/ftp_client_transferred.png) ... and transfer complete. Now what? --- ## Thank you! This material is the result of a collaborative work. Thanks to the [Galaxy Training Network](https://wiki.galaxyproject.org/Teach/GTN) and all the contributors!
