[SOLVED] Logging Confidences in X-Validation

[Skyfaller]

Hi Guys,

okay i have a little problem which i cant seem to solve on my own.
The thing is:
I have a Cross-Validation. As usual in the Training part is the "classifier" (SVM with "calculate confidence") and in the Test part the "apply model" and "performance" Operator.

Now I want to write the confidences to a file. But the outputs of the Cross-Validation doesn't give me the confidences back.

Now i'm trying to write the confidences in the Testing part to a file(write-csv), this seems to work, but unfortunately it overwrites the file in each Step. Which means i only get the last 1/10th of the Data in the File.

In short: Is there any way to write the Output (labelled date) of the "apply model" operator to a file for every iteration of the cross-validation?
If possible to a single file.

Thanks,
Nic
