Hi there, I am expieriencing an error when I try using the static plotting in MultiVolumeExplorer when I want to plot signal drop with time: Traceback (most recent call last): File “C:/Users/Diana/AppData/Local/NA-MIC/Slicer 4.11.20200930/bin/…/lib/Slicer-4.11/qt-loadable-modules/Python/qSlicerM…

Does plotting works correctly if you load the data as a volume sequence and use plotting in Sequences module? [image] If not, please save your scene as .mrb file, upload it somewhere and post the link here so that we can investigate.

Dear Andras, thank you very much for your reply! The interactive plotting works fine for both, the Sequences and MiltiVolumeExplorer modules. The problem appears when I want to plot the chart: [image] I tried the previous stable version (4.10.2) and there it worked fine, the arrays are labelled a…

Can you describe the steps to create this chart (what module you open, what buttons you click)?

I load the data (as a 29 frames MultiVolume by EchoTime) and create a segmentation with 14 segments in ‘SegmentEditor’. Then in ‘Segmentations’ I export as LabelMap. I open the MultiVolumeExplorer, and in interactive plotting everything looks fine, I select ‘Probed label volume’ under ‘Plotting Se…

Hi everyone I encounter the same problem working on a windows system, exactly as described by Diana? Has there been a solution in the meantime? Thanks for your Help best Florian

It works fine, you just need to use a scatter plot of an X and Y series. Line plot just shows one series, which defines the Y values. X values simply contain the indices (0, 1, 2,…).

Thanks for your response! I m not sure if I have understood correctly. But maybe I have also not expressed my problem in enough detail. I have a perfusion dataset and wish to picture signal intesity over time within different ROIs. So scatter plotting is not really an option. How do I have to te…

MultiVolume module is being replaced by Sequences module. We’ll add a dedicated module for time-intensity plots, but for now you can copy-paste this code snippet into Slicer’s Python console to generate the plot. [image]

Hi Andras, unfortunately that didn’t work as easily as I was hoping. I get a couple of error messages which are not that easy to decioher to a newby to Slicer and Python… I am sure these are easy to fix once one has mastered the Slicer Coding structure … but this will take some time… maybe you cou…

Sorry, I forgot to mention that you need to use the latest Slicer Preview Release for this script.
