How to get train_roi_file.txt file?

Hi,
How to get the contents of train_roi_file.txt file? I have my own data set processed from VOTT, where to get the ROI values. pls, explain.

train_roi_file.txt file is simply generated by the following rule:

-Assume we take the image19.jpg
(the final result is |roiAndLabel 137 67 186 184 1 188 69 234 180 1)

for image19 VOTT has generated three files:
- img19.bboxes.labels.tsv - the file contains labels for each rectangle (which is Nokia3310 Nokia3310)
- img19.bboxes.tsv -the file contains two tuples of 4 numbers 137 67 186 184 188 69 234 180
- img19.jpg - original image

The image19.jpg generate one line of the roi file so that it first writes rectangle then writes first label and so on.
As you can see the final result is 137 67 186 184 then 1- means the first label, then 188 69 234 180 then 1 - label.

The roi files is generated when you join each rectangle from bboxes file and each corresponded label number form the labels file.

Hope this help.

Thanks for explaining, Should I join this file manually from each image file?
