InSeis requires Windows Subsystem for Linux (WSL) to run. This allows you to use Linux tools directly on Windows.

Install WSL

1. Open Command Prompt as Administrator (right-click, select "Run as administrator")
2. Run the following command: wsl --install
3. Wait for the installation to complete
4. Restart your computer when prompted
5. After restart, search for "Ubuntu" in the Start menu and launch it
6. Follow the prompts to set up your new Linux environment. You may be asked to create a user account and password
7. Run sudo apt update to ensure all packages are up to date

Note: If you encounter any issues, please refer to the official WSL installation guide: https://learn.microsoft.com/windows/wsl/install

Install Seismic Unix

1. Open the Ubuntu terminal (search for "Ubuntu" in Windows Start menu)
2. Copy and paste this entire command:
3. bash -c "$(wget -qO- https://gist.githubusercontent.com/a-pertuz/2b341bc8af2a37cde820d829f2789d99/raw/install_seismic_unix.sh)"
4. Press Enter and wait for the installation to complete. It may take several minutes

Important: Read and accept the Seismic Unix license agreement when prompted.

Install InSeis

pip install inseis

1. Launch InSeis: Open the application from your Start menu or run inseis in Command Prompt
2. Create a new workflow: The main interface displays available processes on the left and your current workflow on the right
3. Load data: Add a data loading process to your workflow (e.g., "SEGYREAD")
4. Add processing steps: Select and configure processing operations from the available processes list
5. Run your workflow: Click "Run Workflow" to execute all steps in sequence
6. View results: Results will be displayed automatically upon completion

Important note: Seismic Unix uses SU files as its native format. If you need SEGY files for external applications, use the "Convert SU to SEGY" utility in the menu bar after processing.

Interface Overview

The main application window consists of:

• Process Library Panel (Left): Contains all available Seismic Unix processes organized by category
• Workflow Canvas (Center): Where you build and configure your processing workflow
• Parameters Panel (Right): Shows parameters for the currently selected process
• Log Window (Bottom): Displays output and error messages from workflow execution
• Results Viewer (Tab): Visualizes processing results

Creating Workflows

Basic Workflow Structure

1. Input: Data loading processes (e.g., "Load SU File", "SEGYREAD")
2. Processing: Processing operations (filtering, deconvolution, migration, etc.)
3. Output: Results are saved as SU files and displayed within the application

Saving and Loading Workflows

To save your workflow:

1. Click "Workflows" > "Save Workflow..."
2. Enter a name and description

To load a workflow:

1. Click "Workflows" > "Load Workflow..."
2. Select from your saved workflows

Workflow Example: Post-stack Migration and SNR Enhancement

1. Add SEGYREAD: Set input file path

   tape=<input_file.segy>
   

2. Add SEGYCLEAN: Clean unused headers in the SU file

3. Add SUAGC: Automatic gain control

   panel=1, agc=1, wagc=0.75
   

4. Add SUMIX: Compute weighted moving average - trace mix

   mix=.6,1,1,1,.6
   

5. Add SUKTMIG2D: Kirchhoff post-stack time migration

   vfile=<velocity_model.bin>, hoffset=0, dx=25
   

   Requires a velocity model in binary format (see VelRecover)*

6. Add SUPEF: Spike deconvolution for improved vertical resolution

   minlag=0.004, maxlag=0.12, pnoise=0.01
   

7. Add SUFXDECON: Random noise attenuation

   fmin=12, fmax=60, twlen=0.3, ntrw=30, ntrf=4
   

8. Add SUTVBAND: Time-variant bandpass filtering

   tf=0,1.5,2.5 f=10,12,55,60 f=14,16,50,55 f=14,16,45,50
   

WSL Connection Issues

• Ensure WSL is installed: Open PowerShell and type wsl --list. If no distributions are listed, install one using wsl --install
• Verify WSL is running: Open PowerShell and type wsl --list --running
• Restart WSL service: wsl --shutdown and then launch WSL again
• Check network settings if you're accessing remote data

Seismic Unix Not Found

• Check your CWPROOT path in the Configuration menu
• Verify Seismic Unix installation: Run suplane | suximage in WSL
• Check environment variable: echo $CWPROOT should show the SU installation path
• Reinstall if needed using the installation script

Input/Output File Issues

• Check file permissions
• Ensure paths don't contain special characters
• Use forward slashes in file paths
• Verify file formats are supported

Command Failures

• Check the log window for specific error messages
• Verify all required parameters are set
• Ensure input files exist and are accessible
• Check that all processes in the workflow are properly connected

Is InSeis compatible with all versions of Seismic Unix?

InSeis works with Seismic Unix versions 43 and newer. The installer script automatically installs the latest compatible version. If you have an existing installation of Seismic Unix, InSeis will attempt to use it if the path is correctly set in your .bashrc file.

How do I integrate results from SEGYRecover and VELRecover?

To use data from other REV-SEIS tools:

• SEGY files from SEGYRecover can be directly loaded using the "SEGYREAD" process
• Velocity models from VELRecover should be exported in binary format and can be loaded using the "Load Velocity Model" where necessary, for example during migration
• Use the workspace data directory structure to keep your project organized

Does InSeis work on macOS or Linux?

InSeis is designed specifically for Windows with WSL. On macOS or Linux, you can install Seismic Unix directly and use its native command-line interface or GUI alternatives like OpenSeaSeis or BotoSeis.

What is the difference between SU files and SEG-Y files?

SU (Seismic Unix) files and SEG-Y files are both formats for storing seismic data, but with key differences:

• SU files are the native format for Seismic Unix, with a simpler header structure and no EBCDIC header
• SEG-Y files are the industry standard with more extensive headers, including text headers with acquisition information
• InSeis can convert between these formats using the "SEGYREAD" and "SEGYWRITE" processes

Can I run batch processing?

Currently, InSeis processes one workflow at a time. However, you can save workflows and reuse them with different datasets. For batch processing, consider using saved workflows with different input parameters.
