The new dataset

Yesterday, the new data set was posted by the Biology team. The new dataset has been placed in the following location
/usr/sci/crcnsdata/CRCNS/Synapses/data/Refined2_marked_RM2_with_fake/

The salient features of the new dataset are:
  • Image is vertical cross section of rabbit retina. The image dimensions are is 11477 x 18361 (Width x Height) .
  • The markup contains synapses arrows where there are synapses (with 100% confidence) and there are few black pin markups that are non-synapses regions but might be misclassified as Synapses. The number of markups are shown below. The number of markups is quite less than the markups in the previous dataset.
    • Synapses - 67
    • Non-synapses - 16
    • Total Markups - 83
Mosaic Builder: Yesterday, I learnt about the usage of Mosaic Builder from a ROI markup perspective alone. I was able to successfully able to install & run Mosaic Builder on pollux.sci.utah.edu in Visualization Lab. Tried out few things like playing with key words of the markups (Marked all the points as Fake!!), exporting the markups so that my MATLAB & QT code could read it.

SynapsesViewer: I fixed a bug in SynapsesViewer where I had hard coded for the positions of the Markups height of the image so that I can view the synapses in my laptop. I shall explain about the SynapsesViewer in a future post.
