Quick Start

The Illumina InterOp libraries are a set of common routines used for reading InterOp metric files produced by Illumina sequencers including NovaSeq. These libraries are backwards compatible and capable of supporting prior releases of the software, with one exception: GA systems have been excluded.

---

We now support an interface to Python 2.7 (UCS-4) and 3.4-3.6 (see contents below)

---

The InterOp files supported by this library include:

• CorrectedIntMetricsOut.bin
• ErrorMetricsOut.bin
• ExtractionMetricsOut.bin
• ExtendedTileMetricsOut.bin
• ImageMetricsOut.bin
• QMetricsOut.bin
• TileMetricsOut.bin
• IndexMetricsOut.bin
• QMetrics2030Out.bin
• QMetricsByLaneOut.bin
• EmpiricalPhasingMetricsOut.bin

This library is written in C++98 and provides bindings for C# using the SWIG interface. This support includes examples and unit tests for both languages.

Install

Python

Supported versions for binary distribution: Python 2.7 and 3.4-3.6.

You should have NumPy already installed.

$ pip install interop

Test the installation

$ python -m interop --test

If you see this error:

RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa

Then upgrade numpy and try again.

From Source

$ git clone https://github.com/Illumina/interop.git
$ mkdir build
$ cd build
$ cmake ../interop
$ cmake --build .

Building with InterOp

GCC/Clang

g++ example1.cpp -l interop_lib -L <install_dir>/lib64 -I <install_dir>/include

For CLang, just substitute g++ with clang++.

Known Limitations

There are several known limitations to the current library:

1. You cannot build a shared library on Windows. Our CMake build script disallows it for good reason, it currently does not work. You can still use a static library on Windows. There is one caveat, you can build a shared library for the SWIG bindings, e.g. C#.
2. Microsoft .Net less than v4.0.30319 is currently not supported (Same for Mono)
3. MinGW cannot compile the code when ENABLE_BACKWARDS_COMPATIBILITY=ON
4. We do not support Mono on Windows
5. If both Visual Studio and Mono are installed, the build script will only use Visual Studio for C#
6. We do not support 32-bit builds
7. MinGW W64 4.9.x and prior will not link properly
8. Visual Studio 12 2013 is not supported for the C# Bindings (Results in heap corruption)
9. We support .NET Core 2.x or later
10. Big endian systems are currently not supported
11. We do not support compilers earlier than 4.8.x - too many compiler bugs
