Possibility to create a study.. not only a single series

[ilmuska]

At this moment, when the software has converted the nifti image, it closes (moreover without any success message.. but this is an already opened issue). In addition, many times it could be useful not only to create a single series from a single fnifti file, but also many series belonging to a study.. for example in fMRI we need to create a dicom series for each task that was performed.. So, I suggest to add (or at the beginning or at the end) the possibility to create more series belonging to the same study, with the same study id, study instance uid, patient name, birthdate etc.. and varying only series parameters (e.g. series instance uid, series description, series number).
