How to know if all your sequences have been analyzed The Analysis Progress chart is a very useful representation, which shows the step of the analysis in which the sequences in your dataset are found. They can be in different states, each represented by a color: Total: grey Without Analysis: white With IPS: purple With Blast Hits: orange Without Blast
(Show Blast Results, Welcome Part, Create Workflow) running Linux system. This applies to OmicsBox or Blast2GO 5. You need to install some packages depending on your distribution in order to make some parts work. For Ubuntu/Debian: apt-get install libxss1 libgconf-2-4 For Fedora: yum install libXScrnSaver libXScrnSaver.i686 GConf2 For CentOS: yum install libXScrnSaver GConf2 For more information on Show Blast Results
To the Blast2GO installer in Linux systems follow the next steps: 0. Open a terminal in the folder where you have downloaded the installer. 1. Unzip the file: tar -xvf Blast2GO_unix_X_X_XX.zip 2. Make sure the .sh file has execution permissions: chmod +x Blast2GO_unix_X_X_XX.sh 3. Execute the .sh file: ./Blast2GO_unix_X_X_XX.sh An installation wizard should open. Just follow the instructions on the
This article describes how you can get OmicsBox installed in a central computer where multiple users have access and what you need to configure so that it doesn’t ask for the License key for every new user and the updates are performed centrally. 0.0. You need a Unix user group that common to all the users that will execute OmicsBox.
The error looks like: “Critical: (110.6) CNcbiRegistry: Syntax error in system-wide configuration file: NCBI C++ Exception: “……….\src\corelib\ncbireg.cpp”, line 660: Error: ncbi::IRWRegistry ::x_Read() – Badly placed ‘\’ in the registry value: ‘ROOT=J:\nASNLOAD=J:\BioEdi t\tables\nDATA=J:\BioEdit\tables\’ (m_Pos = 4)Error: NCBI C++ Exception: “……….\src\corelib\ncbireg.cpp”, line 660: Error: ncbi::IRWRegistry ::x_Read() – Badly placed ‘\’ in the registry value: ‘ROOT=J:\nASNLOAD=J:\BioEdi t\tables\nDATA=J:\BioEdit\tables\’ (m_Pos = 4)” This error is
Reformat/adapt Blast XML results against a custom UniProt sequence database to generate a species distribution chart Problem: Empty species distribution chart Solution: Reformat your SwissProt/UniProt blast XML results The species distribution chart is a good way to visualise the species found for all blast hits for a given dataset. It is possible to generate this chart with OmicsBox from the toolbar: functional
OmicsBox allows running Blast locally. The blast algorithm will run on the user’s computer against a database that is installed locally. In order to do so, we have to either download a pre-formatted NCBI database or format our own database (see this tutorial until step 3). Pre-formatted databases can be downloaded directly from the NCBI ftp or via a Perl script provided by
Update: Since Blast2GO v.4 or in OmicsBox you can create your Blast Database directly from within the application. See screenshots below. Note: This tutorial is based on the NCBI blast binaries released in 2014 and some parameters might have changed since then If you want to blast your sequences against an own own database you need to create a custom
