Help Needed To Run Seal For Genome Mapping.

Hello, I managed to build an index file from the reference genome using Seal. Now I am trying to run Seqal but I am running into errors.

./seqal /user/hadoop/seal/synthetic_prq1 /user/hadoop/seal_output /mnt/shared/data/version0.5.x/index.tar
Traceback (most recent call last):
File "./seqal", line 39, in <module>
from bl.mr.seq.seqal.seqal_run import SeqalRun
File "/mnt/shared/seal-0.3.2-src/build/bl/mr/seq/seqal/__init__.py", line 25, in <module>
from pydoop.pipes import runTask, Factory
ImportError: No module named pydoop.pipes

I have a hadoop cluster of 1 master and 5 slaves (Version 1.0.3). I have installed pydoop on the shared nfs folder in the cluster.

Can anyone please tell me how to get past this error?

Thanks, Ashwin
