> I want to convert a sequence file into a map file. So i used the fix function
> provided by MapFile to create the index file. Also i set the indexInterval as
> 1 since i want to index each record in the data file. However, i found that
> the position of the first record in the data file was incorrectly indexed by
> the index file. And it turns out that the fix function sets the position of
> the first record as 0. This is wrong because the reader of the data sequence
> file has already read the head and the position should be the length of the
> head. So, i tried to set the position as the correct value and it now works.
