I'm using the Classification Workflow for a supervised object-based classification in ENVI 5.5.2, and whenever I load a pre-made point shapefile as Training Data the system freezes after the training data is loaded, and won't run to the next step in the workflow.
No matter how small I clip the image, or how simple the training data shapefile points are (i.e. minimal attribute columns), it just freezes up and won't progress to the next step. Has anyone else encountered any issue like this, or know what I could try to get it working? If I manually make my own training data points within ENVI it progresses to the segmentation and classification stages without any problem, so it must be something to do with loading up a point shapefile as training data. My training data set has about 400 points, but I've experimented with much fewer with no success. There are 12 ROIs for the classification. Any help very much appreciated, thanks!
