The images belonging to the
MFISH dataset are not ordered in a hierachy of directories defined as project/slides/field_xy/fluorochromes/image.
To navigate through that images database as in the
previous post, the images need to be reordered.
The central part of the following image displays the original images arrangement, the right side shows the images after reordering. We have for example a slide called A01 belonging to the
ASI MFISH dataset . For this slide, five xy fields were taken (from 01 to 05) . The folder called Kar, contains the segmented image (the chromosome 1 is set to grey level and so on).
Three dirty python scripts (
pylint 1.76/10 !) reorder the MFISH dataset. One for each images subset (
ASI,
PSI or Vysis). Prior running the scripts:
- make three folders (ASI, PSI, Vysis) in the top directory (MFISH)
- select all the slides whose name start by 'A', cut and copy them in the ASI folder and so on the the PSI slides (starting by a 'P') and the Vysis slides (starting by a 'V').
- modify the path to the top directory inside the script and run the ASI script to reorder the images from ASI images subset.
- run the PSI script ...
- run the Vysis script.
To modify the path find the line:
path='/home/simon/MFISH/'+'ASI'
Modify it as:
path='/fit/to/your/path/MFISH/'+'ASI'
The pygmentized ASI script is shown:
