Failed to find UseExternalRanges

Hi, I'm trying test my dataset in your toolkit using some algorithms. When I run my training using a file created (my dataset) according with your description .grt file, it shows a message:

[ERROR TSCD] loadDatasetFromFile(std::string filename) - Failed to find UseExternalRanges!
Failed to load training data!

My dataset:

GRT_LABELLED_TIME_SERIES_CLASSIFICATION_DATA_FILE_V1.0
DatasetName: UFBAGRDataset
InfoText: This dataset contains 7 gestures (g1,g2,g3,g4,g5,g6,g7), totalizing 1099 executions.
NumDimensions: 3
TotalNumTrainingExamples: 600
NumberOfClasses: 7

I also have some doubts:

    1. Can I use 3D vector of float values in time series?
    1. Can I use the same description file with others algorithms/models (HMM,SVM)?
    1. My gestures are performed with two hands, so I created the time series first putting all left hand positions and after the right. That's right?

Well, I found the problem. The documentation doesn't have information about the usage of the different versions of the dataset description file like:

GRT_LABELLED_TIME_SERIES_CLASSIFICATION_DATA_FILE_V1.0
GRT_LABELLED_CLASSIFICATION_DATA_FILE_V1.0

Answering the question that myself asked:

Q1 - Can I use 3D vector of float values in time series?

R: Yes, you need set the NumDimensions: 3

Q2 - Can I use the same description file with others algorithms/models (HMM,SVM)?

R: No, you can't. The description file depends of the algorithm.

Q3 - My gestures are performed with two hands, so I created the time series first putting all left hand positions and after the right. That's right?

R: Well, I don't know. I hope that someone answer this question.

Anyway, I hope that this can help.
