Stack Exchange — bioinformatics.stackexchange.com

The content of bioinformatics.stackexchange.com (https://bioinformatics.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 34,111 rows: 14,106 posts (6,093 questions, 7,551 answers, 226 tag wiki excerpts, 226 tag wikis, 6 posts of type 6 and 4 posts of type 7) and 20,005 comments, written between 16 May 2017 and 31 March 2024. Beside it are 14,791 user accounts, 42,878 votes, 20,242 badges awarded, 536 tags, 46,084 post revisions and 508 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 68 rows.
