The attached script (python) simply convert every files in a given directory (dir=) into a new file which should be more similar to the usual ISI format that one can download on the website.
The final structure of the file is not perfectly mimicking every features nor every fields of the regular isi exports. But the conversion may be sufficient for most uses. Otherwise, the convsersion script can certainly be enhanced to allow a better fit with the original isi files.
Two examples files are also provided. The one terminating with '.isi' is the output of the script applied to the other file which directly comes from the data challenge raw data repository.
