HI, Thanks for your reply, I did a bit of digging in. Here is when these errors show up and also when they don’t
I create sparse labels outside of Ilastik and then import them in. When I do that the Qaxis Validator error pops up either later or sooner (in Pixel classification workflow) but is harmless as it does not interfere with the training or the saving operation and I have always ignored it.
I used the joint pixel and object classification workflow for the next error.
2A) In this If I select all features in the first go and then in subset of features pick only some and keep computing, the export works fine.
2B) But If I am not happy with the feature selection and go back in the menu to select more subset of features It starts popping up errors like “index 4 is out of bounds for axis 1 with size 3” and then when I try to export the results, the error as I posted above prevents me from saving the results. and I have no idea what I did wrong,
2C) If I use pixel classification first and then object classification second (Now I do the steps in your reply till 4 and all is ok) than using the combined one, all the above operations yield no errors.
I am using Ilastik 1.3.0 and the QAxis error was always there with the import Labels operation but the second error in the joint workflow is something I am seeing for the first time, coz of going back and forth in selecting the features. If somebody else can reproduce this in the pixel + object classification workflow by repeating these steps it would help in getting to know why these operations cause this to happen.
