This function is not part of Brainstorm/Nirstorm, I'm not sure how we can help you with this.
Hello,
It seems that. you are trying to convert some data from NIRx to Homer format (.nirs). If you send me the data and the script you are trying to use, i might give a try; However, i think that NIRx might be able to provide more help than i do.
