(released in 2019) have added stability and features like soft parameter limits. Licensed users can generally download these updates for free from the Interpex support page

The software excels at converting apparent resistivity curves (measured in ohm-m) into a layered earth model—typically 2 to 7 layers—showing true resistivity and thickness for each layer. This output is essential for: interpex ix1d v350

While newer versions and 2D/3D software exist, v3.50 remains a historically significant and widely used version in the geophysics community due to its stability and robust inversion algorithms. (released in 2019) have added stability and features

Beyond its mathematical core, the software’s practical utility is enhanced by several key features. The “forward modeling” mode is exceptional for educational purposes and hypothesis testing, allowing users to build synthetic geological models (e.g., a resistive layer over a conductive aquifer) and instantly view the resulting apparent resistivity curve. Critically, the V350 version introduced advanced capabilities like the handling of induced polarization (IP) effects, allowing for the joint interpretation of resistivity and chargeability data—a powerful combination for mineral exploration. The ability to import and export data in multiple formats, alongside a manual "picking" routine to estimate asymptotic resistivities, streamlines what would otherwise be tedious calculations.

As a legacy application (commonly run on Windows 95 through Windows XP architectures), IX1D v3.50 is lightweight by modern standards. It is often run on modern Windows 10/11 systems using or within a Virtual Machine (VM).
