pypulseqpp-seqeyes

SeqEyes, the Pulseq sequence viewer, built for pypulseqpp's Sequence.plot. It is installed with pip install 'pypulseqpp[plot]' and is not needed for anything else.

The wheel carries the SeqEyes program and no Qt: it runs on the Qt that PySide6-Essentials installs. pypulseqpp-seqeyes file.seq opens a file from the command line, with SeqEyes' own options.

Linux

PySide6's Qt draws with the system's display libraries. A desktop has them; a bare server or container needs, on Debian or Ubuntu,

# For offscreen rendering with QT_QPA_PLATFORM=offscreen
sudo apt install libegl1 libgl1 libx11-6 libdbus-1-3 libfontconfig1 \
  libfreetype6 libglib2.0-0 libxkbcommon0
# And to open a window under X11 (Wayland needs none of these)
sudo apt install libx11-xcb1 libxkbcommon-x11-0 libxcb1 libxcb-cursor0 \
  libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 \
  libxcb-render-util0 libxcb-render0 libxcb-shape0 libxcb-shm0 \
  libxcb-sync1 libxcb-util1 libxcb-xfixes0 libxcb-xkb1

libxcb-cursor0 is the one an Ubuntu desktop may lack: Qt needs it to open an X11 window, and says so if it is missing.

Licence

GPL-3.0-or-later. SeqEyes is BSD-3-Clause (seqeyes/LICENSE, and seqeyes/licenses/license_safe_pns for its PNS model); QCustomPlot, the plotting widget compiled into it, is GPL-3.0-or-later, so the program they make is too. pypulseqpp itself is MIT and does not depend on this package.

Building

SeqEyes is the submodule in seqeyes/, pinned to a release and built as it stands. A build needs Qt 6.8 or later, found through CMAKE_PREFIX_PATH:

git submodule update --init --recursive
CMAKE_PREFIX_PATH=/path/to/Qt/6.8.3/gcc_64 pip install ./viewer

The release wheels are built by cibuildwheel, configured in pyproject.toml.
