Please refer to the following link for details. I am planning to send an e-mail to the conference chairs regarding my withdrawal. I wanted to seek help from the experts in the community for drafting the e-mail since I believe that it should be very carefully crafted since it is going to cause inconvenience to the conference committee(even though I haven't submitted the copyright form and the paperwork hasn't started yet).
What are the details that I should include in my e-mail? Do I need to be specific about the error or just write that I've discovered an error in the paper(considering the fact that I will continue to work on the paper and submit it to a journal)? Also, what possible responses should I expect from them? Any help would be highly appreciated. I am having problems sleeping since the day I've discovered the error and cannot concentrate on my work. I just want to make the fact explicit and move ahead.
