FLAIR segmentation not running for low-grade glioma mode about raidionics

Perfect, yes, that ‘models purge’ fixed it, thank you.

Great!

Alternatively, you can also tick the Models update option in the Settings panel. It will force the system to check if a new model is available everytime the segmentation task is performed, and if so the latest model will be downloaded.

Hi @natalievpj,
There is no specific workaround for running the low-grade glioma segmentation model on FLAIR data. The process you describe seems correct, and it should work exactly like for glioblastoma use-cases.

Can you open the Logs window after an unsuccessful segmentation attempt, and copy paste the content of the window in here? You will find it in the top menu-bar, under Settings > Logs, of you can simply use the cmd(⌘) + L shortcut on Mac.

Good morning, thanks for the quick reply. Ah it looks like there is missing LGG_pipeline according to the logs. Please see enclosed below (this is the M1 chip laptop version, but if I recall, this has never worked for the older laptop pre-M1 either with the earlier release version of Raidionics).

The pipeline file is downloaded at the same time as the segmentation model itself. However, if a new version of Raidionics is installed, the previous models folder on disk is not being deleted and old models are likely to then be incompatible because of a caching mechanism (which is an issue we have to fix).

In order to allow for a proper re-download of all models, especially after installing a new version of the software, you have to open the Settings panel (cmd(⌘) + P), and in System settings you have to click the Models purge option (with a trash bin icon).

Dear David Thanks for your help in the past. I wondered if you could advise with some difficulty locating/manually downloading the required models when these are not found through the normal package install (or via a system models>purge)? I recently downloaded v1.2.2 for MacOS ARM (M1 Pro running Ventura 13.3.1). This was working fine until, while making my way through a list of tumours, Raidionics did not want to accept a particular image, nor a few subsequent ones (FLAIRs). This has happened in the past when working through many patients, so I restarted Raidionics (no success). I also tried a different tumour type (calling a T1ce) which opened ok but would not segment. The log stated it could not find the model .json. I tried the models/purge (with models update option ticked on). No success. I tried a full delete of the Raidionics icon from Apps folder and redownloading (with laptop reboot). Same issue (no model found and not fixed by a purge + resegment attempt). I used the terminal to navigate to /Users/me/.raidionics/resources/models which does not seem to have anything in it (‘ls’ returns no result). So I tried a rm -rf of .radionics there, and again a full redownload& package install (1.2.2-macOS-arm64.pkg). Each time the software downloads ok and I can open it, but it seems cannot find the segmentation models. The images do segment ok in version 1.2 that I have still available on an older laptop. Is there a git pull for missing files or another solution that you might suggest trying? Thanks so much, hope all is well Natalie

Hi @natalievpj,

I have just tried again the same process as you described above on an M1 machine. I've deleted the .raidionics folder and installed the latest v1.2.2. version for MacOS ARM, loaded a new FLAIR image, and ran the segmentation task, and everything worked fine.

As I can't seem to reproduce the issue, it is difficult to get an idea as to what might go wrong on your own machine. If no model is being downloaded automatically at all, it might be related to some internet, firewall, or Google Drive related issues. In that case, you can try to manually download the models as explained below.
I have not ran extensive testing when having many patients opened at the same time, but you more often experience issues in such use-case compared to opening a few patients?

Simple test

If you download the provided test data sample, available through the GUI buy clicking File > Download test data, and then load the T1 MRI scan available in the Raw subfolder (might have to adjust the sequence type to T1-CE in the right-hand side panel), can you run the preoperative segmentation task for Glioblastoma?

Models manual download

All the models used by Raidionics can indeed be manually downloaded at the following link, more specifically the LGG preop segmentation model is available here. After downloading the archive, you simply need to extract the content and place the obtained folder inside ~/.raidionics/resources/models/.

FLAIR images

I have noticed some issues when the intensity range for FLAIR images is within [0, 255], as the image might be confused with an annotation mask. Was it the case for the images you had trouble segmenting? You can have a look at the intensity range/histogram by clicking the Contrast button associated with the MRI scan to the right-hand side panel of the interface.

Settings/Preferences

After deleting the ~/.raidionics folder, all user preferences should have been set to their default values. But if you open the settings panel (through cmd(⌘) + P), and navigate Processing-Segmentation > Segmentation models, if the Output classes is not set to Tumor, the multiclass model will require multiple MRI scans as input (T1-w, T1-CE, T2, and FLAIR) for running successfully over the glioblastoma/low-grade glioma tumor types.

Those are ideas/suggestions that come to mind, let me know if you manage to solve your issue!

Hi Thanks very much for the response and helpful details. Models – great thank you. I have manually downloaded these and both glioblastoma and low grade segmentation now run again. I don’t know why it fails to transfer with the original download/models purge, but manual download solved it! Multiple patients sequentially – the behaviour reminds me a bit of a memory clearing problem. The sweet spot seems to be around 8 or 10 patients, I do them one at a time (load new patient, segment, save, close completely (don’t save), load a new patient, etc. At some point (around the 8th or 10th time or so), I find Raidionics crashes. It is either totally crashes (and closes) or it complains about an image when the image is fine (if I close Raidionics and reopen the same image then its fine). Just as user feedback. FLAIR – I can’t check using the ‘contrast’ setting in Raidionics unfortunately because the image will never open at all (error message is ”unable to load FLAIR.nii.gz. Error message: no MRI volume has been imported yet. Mandatory for important an annotation”.). However I’ve checked the intensity range differently (fslstats) and yes absolutely - the range is 0 – 200. Another FLAIR that does open successfully has indeed a higher max value range. If you happen to implement a workaround I will gladly try again (I’ve just segmented in ITK snap for now, but have kept a note of which patients these were).

Great!
I will close this issue for now, but will further investigate as to why the automatic download of models can sometimes fail.

I have also opened two other issues for the problems you mentioned (#69 and #70), so it will be easier to follow-up and get notified when a new release fixing the problems is available.
