The CyVerse App Store is currently being restructured, and apps are being moved to an HPC environment. During this transition, users may occasionally be unable to locate or use apps that are listed in our tutorials. In many cases, these apps can be located by searching them using the search bar at the top of the Apps window in the DE. To increase the chance for search success, try not searching the entire app name and version number but only the portion that refers to the app's function or origin (e.g. 'SOAPdenovo' instead of 'SOAPdenovo-Trans 1.01').

Also, as part of the 2.8 app categorization, a number of apps were deprecated and are no longer available, and there is no longer an Archive category. You can search for a suitable replacement in the List of Applications in this window, or search on an app name or tool used for an app in the Apps window search field. If you need an app reinstated, please contact support@cyverse.org.

Rationale and background

Modify_GFF_Coordinates app will add bp to either side of the start and stop coordinates of the gff file. The user can select the delimiter (eg, gene, exon etc) as well as the number of base pairs to add to the gff file

Prerequisites

  1. A CyVerse account (Register for a CyVerse account at https://user.cyverse.org/).

  2. An up-to-date Java-enabled web browser. (Firefox recommended. If you wish to work with your own large datasets and upload them using iCommands, Chrome is not suitable due to its issues in utilizing 64-bit Java.)

  3. Inputs: 
    2. Delimiter: The feature of gff file that you want to add the bp to. Ex: gene)
    3. Base pairs: The number of base pairs to be added to either side of start and stop coordinates in the gff file
  4. Output File name: Name of the output file
