itaps-parallel A question about iMeshP interface functions

[txie at scorec.rpi.edu]

Hi, Vitus,

Thanks for using FMDB.


Currently you can download the latest version of FMDB from our website
through anonymous access with the following command:

svn checkout https://gforge.scorec.rpi.edu/svn/fmdb/trunk  YOUR_FMDB_DIR


Please let me know if you have any problems about FMDB. Thanks.

Regards,

Ting
