Hello,

I am trying to use the Pkmodeling extension to analyze DCE-MRI images and I am receiving the error below:

itk::ExceptionObject (0000004C75F13E18)  
Location: “unknown”  
File: D:\D\N\S481-E-b\PkModeling\CLI\PkModeling.cxx  
Line: 244  
Description: itk::ERROR: itk::ERROR: Unrecognized frame identifying DICOM tag name Time Image C:/Users/brand/AppData/Local/Temp/Slicer/BCGEI\_vtkMRMLMultiVolumeNodeC.nrrd does not contain sufficient attributes to support algorithms.

I believe this is due to my DICOM series not having a trigger time tag. However, I am a fairly novice user and do not know how to correct this missing information.

Any help is appreciated!

Can you include the following details:

- did you import the DCE MRI into Slicer using DICOM Browser or MultiVolumeImporter?
- what version of Slicer do you use?

I have tried to use both the DICOM browser and MultiVolumeImporter and received the same error. I’m using version 4.8.1 for windows.

I believe this issue was fixed this April, after 4.8.1 release in this commit: [https://github.com/QIICR/PkModeling/commit/8e597589e761bde1ab17f17126ac002527cbd28d](https://github.com/QIICR/PkModeling/commit/8e597589e761bde1ab17f17126ac002527cbd28d). Can you please try if the nightly build works for you?

The nightly build works and I am no longer receiving the error. Thank you for your time and advice!
