A simple viewer for Sanger trace file made with Qt5. Supports AB1 and SCF 3.0 file formats. It has regular expression pattern finder and can export trace as SVG vector image.
Despite the major use of Next Generation Sequencing, the Sanger method is still widely used in genetic labs as the gold standard to read target DNA sequences. Very few opensource software is available to explore Sanger trace data and most of labs staff still rely on proprietary software. Moreover, they are not always user-friendly and lack modern look and feel.
4peaks is a software widely used by biologists that benefits from a nice User interface. Sadly, it is only available on MacOS and source code is not opened to community enhancement. Seqtrace is the only standalone and opensource application we could find. However, it is written with GTK framework in Python 2, the latter being deprecated and slower than C++.
Linux binary is available as AppImage. Download the AppImage from here. For ubuntu >=21.04, Download this one here
Run it as follow:
chmod +x cutepeaks-0.2.0-linux-x86_64.appimage
./cutepeaks-0.2.0-linux-x86_64.appimage
Cutepeaks is available as a flatpak
flatpak install flathub io.github.labsquare.CutePeaks
flatpak run io.github.labsquare.CutePeaks
From website: Download Qt ≥ 5.7 from https://www.qt.io/. Don't forget to check QtChart module during installation.
From Ubuntu: Qt 5.7 is not yet available with Ubuntu. But you can add a PPA to your software system. For exemple for Xenial:
sudo add-apt-repository ppa:beineri/opt-qt57-xenial
sudo apt install qt57base qt57charts-no-lgpl
source /opt/qt57/bin/qt57-env.sh
From Fedora: Qt 5.7 is available.
sudo dnf install qt5-qtbase-devel qt5-qtcharts-devel
Be sure you have the correct version of Qt (≥ 5.7) by using qmake --version. For exemple, if you have installed Qt from ppa:beineri, you will find it under /opt/qt57/bin/qmake. Then launch the compilation from CutePeaks folder as follow.
/opt/qt57/bin/qmake --version
/opt/qt57/bin/qmake
make
sudo make install
CutePeaks supports following trace file formats:
- *.ab1
- *.scf
Example files are available here:
https://github.com/labsquare/CutePeaks/tree/master/examples
You can open those files from cutepeaks by clicking on open from the File menu.
Once the file is open, cutepeaks allows you to :
- Explore the trace from a scroll area. ( Finger geasture are supported with touch screen)
- Scale the trace horizontally or vertically using 2 sliders at the bottom right.
- Select a subsequence with the mouse as with any text editor. Then you can cut or copy to the clipboard
- Make the reverse complement from the edit menu
- Display Sequence and metadata from the view menu
- Search for a regular expression pattern. Open the "Find Sequence..." from the edit menu
- Export trace or sequence to different format. ( e.g: Fasta, CSV, SVG or PNG image )
