Error "Negative position" reading .AIM files

[ludo]

Dear all,

I'm trying to read a .AIM file using bio-formats (v5.0.2) and the function bfopen.m. The file is 2.2GB and contains 1115 slices. The function successfully reads the slices #1 to #1031 (using the function bfGetPlane.m), but give me the error below from slice #1032 to #1115. I uploaded the file on the OMERO.qa plateform
http://qa.openmicroscopy.org.uk/qa/feedback/9541/

Thanks in advance for your help!!

Java exception occurred:
java.lang.IllegalArgumentException: Negative position

Thank you for reporting this problem, and for uploading the relevant file. A fix for the problem is under review:

https://github.com/openmicroscopy/bioformats/pull/1347

This fix is expected to be included in the 5.1.0 release of Bio-Formats/OMERO.

Thank you very much for your answer. I downloaded the source code, include the fix you mentioned in your reply, compile the code... and now it works perfectly!
Thanks again!
