I tried running the following experiment: https://github.com/castorini/anserini/blob/master/docs/experiments-msmarco-passage.md . I got an empty file at runs/run.msmarco-passage.dev.bm25.tsv .

Also according to the logs, the TopicReader was downloading topics that had already been prepared by me.:
INFO [pool-2-thread-1] topicreader.TopicReader (TopicReader.java:229) - Downloading topics from https://raw.githubusercontent.com/castorini/anserini-tools/master/topics-and-qrels/topics.msmarco-passage.dev-subset.txt

Setting -topicReader from TsvInt to TsvString fixes the problem,

Am I the only one who has had this problem?
