Progress

Introduction

Date: November 3-7, 2014

Location:

German Cancer Research Center, Heidelberg, Germany

More details to follow.

Goal: A follow on to the wildly successful previous hackfests!

Requirements: Attendees must be willing to spend their time during the event writing ctk code that contributes to the main ctk roadmap. This means spending the week immersed in C++, Qt, DCMTK, CMake, and related technologies. People who do not feel qualified for this task are politely not invited :)

Group size: Maximum 20 participants so we can have a manageable working meeting. The organizing committee will invite and select participants based on input from TheTeam.

Site Hosts: Marco Nolden, Sascha Zelzer, Ivo Wolf

Organizing Committee: Steve Pieper, Ivo Wolf, Stephen Aylward

Future Events: Future hackfests will be announced in advance, and we hope lots of people will be interested in participating. The venue and activities at future hackfests will be determined based on the number of active participants in the project. We welcome participation via the CTK email lists, the source code repository, and this website.

Note Note: There were also other invitations sent to active people on the community, and people who recently showed interest. When their intent will be known they will be added to the list.

Preparation

Developers should bring a laptop with the current CTK source code downloaded and built.

Use the CTK developers mailing list to discuss build issues and topics for ongoing work.

Phone conferences have been scheduled in the weeks leading to the event:

Topics and Projects

Consider reading Contributing_to_CTK#Integrate_your_new_feature

Reminder: when integrating branches, remember to use --log --no-ff when merging.

We plan to have concrete hacking topics as well as dedicated discussions in smaller groups. People are encouraged to show their interest in a particular subject by adding their name to the list below.

Hacking Topics

Infrastructure

  • Qt5 migration (Christian)
    • compile and run on Mac
  • Packaging / install support (Marco, Jc)
  • Fix issue related to Artichoke and improve documentation (Jc)
  • Dashboard
    • General Situation: Continuous/Nightly clients, coverage
    • Configurations: Qt4, Qt5, etc.
    • Travis CI (Sascha, Steve)
  • Incomplete doxygen on the website (Christian)
  • Component / target oriented build system (Jc, Sascha)
  • Review commontk/* repositories (delete/update/etc.)
  • Check support for MacOS 10.10

DICOM

  • dcmtk Features
    • Support building with emscripten, pinnacle
    • Multi-frame support (Steve, Christian, Michael)
    • SEG support
      • Investigate compatibility of DCMTK seg functionality with BrainLab segmentations; sample dataset (QIICR community, Steve has access) - RLE compressed
      • Investigate DCMTK RLE compression tools applied to segmentations; trying to apply it to sample objects generates "F: No conversion to transfer syntax RLE Lossless possible!" error; SPL segmentation dataset example, PET segmentation example
  • Making CLIs read and write valid DICOM (Steve, Michael)
  • ctkDICOM improvments (Ralf); discussed ideas:
    • Introduce "compact and detailed view mode" to ctkDICOMTableView and ctkDICOMTableManager. Basic idea is that you can give the widgets a list of "high priority" tags -> in compact mode all columns of non priority tags will be filter. You can define the active mode via property / slot (to e.g. easily connect it with a control widget signal).
    • Refactoring of one unified "search definition widget" and separated generators for "dicom q/r" and sql statement that use the search definition. This would give the possibility for instance to use the same search widget in different places (e.g. in the ctkDICOMQueryRetrieveWidget or ctkDICOMTableManager)

XNAT

  • Improve and extend the XNAT API (Sascha Zelzer, Miklos Espak, Ralf)
    • Python Wrapping (Sascha, Nicolas)
    • Data editing (post-poned)
    • Uploading (Andreas, Ivo)
    • Caching (Miklos, (Ralf))
    • C++ VS XNAT data model (Nicolas, Andreas)
    • Filtered data query based on data type and/or properties (Miklos)
    • Launch pipelines (remote) and follow progress (Miklos)

CLI

  • Make it customisable what options to generate to the final command (Gergely Zombori)
  • Finalize integration of CTK CLI frontend into Slicer and investigate how to integrate the backend (Jc)
  • Improved entry point / documentation for CLI users & developers

Documentation & Presentation

  • Nice landing page?
  • Improve wiki? Something different?

Travel & Hotel

Local contacts

  • Marco Nolden (m.nolden@dkfz-heidelberg.de)
  • Sascha Zelzer (s.zelzer@dkfz-heidelberg.de) Sascha phone.png
  • Andreas Fetzer (a.fetzer@dkfz-heidelberg.de)

Transportation

It takes about an hour from Frankfurt Airport (FRA) to Heidelberg Main Station with one change in Mannheim. If you stay in the Old Town you can also look for connections going to "Heidelberg Altstadt". You can look it up at Deutsche Bahn, but they run quite frequently.

Local: from the Old Town, "Universitätsplatz", runs bus number 32 (geographic map) via Main Station to DKFZ, exit at "Chirurgische Klinik", bus direction is "Neuenheim". After you exit, DKFZ is on your right.

During the day the bus runs every 10 minutes in both directions, timetables are also available at VRN.

To Frankfurt Airport

The German Railways is affected by a strike from Thursday to Monday morning. Trains will operate on a limited basis - check the website of Deutsch Bahn.

You may also use a Shuttle Bus departing from the Crown Plaza in Heidelberg. It is recommended to book online as early as possible.

Lodging

We recommend to stay in the historic Old Town. There is an easy direct bus ride every 10 minutes from there to DKFZ.

We have reserved a number of rooms at the Holländer Hof (map) hotel! Please use "CTK 2014" when you do a reservation there. Of course there are plenty of other hotels in that area, e.g. Goldener Hecht or the oldest house in town, Hotel zum Ritter.

Meeting Room

The full address for the DKFZ is

Deutsches Krebsforschungszentrum
Im Neuenheimer Feld 280
69120 Heidelberg

We will meet in the main building on the second floor (European counting!). The cryptic room number is D0.02.032. Follow the description below to find it.

When leaving bus 32, you will see something similar to

DKFZ Bus.jpg

The large building on the right is the DKFZ main bulding

Walk through the main entrance and follow the map

Ask the nice guys at the reception or call us in case of any problems.

Weather

November is a rather wet month. Average weather in Heidelberg

Food

Plan on having breakfast at your hotel before the meeting. Please email the organizers if you have any allergies or dietary restrictions.

Being a university and hospital campus, there are several lunch possibilities, including cafeterias, a students mensa, and two restaurants.
