CTK-Hackfest-Nov-2014

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.

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)

• Anonymization (Andreas Fetzer, Marco, Steve, Stefan, Ralf)
  • Client-side options: gdcmanon, dcmtk (?), dcmjs, DicomCleaner, CTP...
  • Testing can use File:PieperMRI.tar.gz
  • Goal is to de-identify with various tools and compare results with supplement 142 of the DICOM standard.
  • There is a separate page, which provides an overview of existing de-identification tools: DICOM de-identification tool overview

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?

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.

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

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.
