Download OpendTect

Required System Libraries (Linux)

OpendTect requires the xcb system libraries. Check whether they are installed:

• Debian/Ubuntu: sudo apt list --installed | grep xcb
• RHEL/CentOS/Rocky: yum list installed | grep xcb
• OpenSUSE: zypper search --installed-only xcb

If missing, install them:

• Debian/Ubuntu: sudo apt install libx11-xcb1 libxcb-util1 libxcb1
• RHEL/CentOS/Rocky: yum install libxcb xcb-util xcb-util-image xcb-util-keysyms xcb-util-renderutil xcb-util-wm
• OpenSUSE: zypper install libX11-xcb1 libxcb-util1 libxcb1

Installation via Installation Manager

1. Download the Installation Manager for your platform using the links above.
2. Open a terminal window and change directory to where the installer was downloaded.
3. Run sh OpendTect_Installer_lux64.sh. Note: csh or tcsh must be installed to run the installer.
4. The installer unpacks to /tmp and launches the OpendTect Installation Manager wizard.
5. For a fresh install, keep the proposed base directory or pick your own. Commercial and free products must be installed in separate folders (e.g. OpendTectPro and OpendTectFree).
6. Select the package type — OpendTect Pro (Commercial) or OpendTect (Free). Miniconda3 is auto-selected with both. Documentation and Developer Tools can be added later.
7. In the Package Manager, toggle individual packages or pick a package combination from the top list. Click an item to view its description on the right.
8. For the Machine Learning plugin, select Python CUDA 11 (GPU) for Nvidia GPU training, or Python MKL (CPU) for CPU-only. The base Miniconda3 environment is always installed.
9. Click Install. Packages download from the server and unpack to the installation path.
10. If a download is interrupted, the installer offers options to increase the timeout, change the download server, or adjust Proxy settings. Temporarily disabling the Linux firewall or SELinux can also help.
11. To start OpendTect, change directory into your installation (e.g. ~/OpendTectPro/7.0.0) and run ./start_dtect.

Installer Logging

If something goes wrong during installation, check the log files: /tmp/your_username_od_instmgr_install_log.txt or /tmp/your_username_od_instmgr_updcheck_log.txt.
