This turns out to be a sinedon error since myami change of using package.module instead of module.
The same command works with the old sinedon.

Testing Command:
tomomaker.py --session=10feb05c --bin=4 --alignerid=1 --projectid=256 --runname=full2 --thickness=20 --description="test recon" --commit

sinedon.data.DataAccessError: referenced data can not be found: DataReference[class: ApTomoAlignmentRunData, dmid: None, dbid: 1, referent: None]

Additional test:
1. printing alignerdata['alignrun'] from apTomo.py before it is called to be used at line 67 gave the same error.

2. I assigned ap256 to sinedon appiondata and run python command line as follows with no error:

>>> from appionlib import appiondata
>>> q = appiondata.ApTomoAlignerParamsData()
>>> alignerid=1
>>> alignerdata = q.direct_query(alignerid)
>>> alignerdata['alignrun']

Anchi, I added a new function to apProject to help test this and it worked for me.

try:

from appionlib import apProject
from appionlib import apTomo
apProject.setDBfromProjectId(256)
apTomo.getTiltListFromAligner(1)

Results:
[{session: DataReference[class: SessionData, dmid: None, dbid: 7334, referent: None], tilt min: -60.0, tilt max: 60.0, tilt start: 0.0, tilt step: -2.0, number: 15}]

Are you sure this is a sinedon problem?

Ah, nevermind. The above commands work in Fedora 12, but fail in CentOS:

I cannot reproduce this exception using my sandbox as PYTHONPATH. Since both Neil and Anchi have cases of it working and not working, can you both post your python path (print sys.path at the beginning of your script) both when it is working and not working. Maybe we can find a difference. In my case, I have not added anything else to PYTHONPATH except for the myami main directory (which includes a symlink to appionlib for completeness).

I think it is a pythonpath problem:

Here is mine on x64 machines that gave me the problem:
PYTHONPATH=/home/acheng/myami/64build:/home/acheng/myami:/home/acheng/myami/leginon:/home/acheng/myami/appion:/ami/sw/packages/EMAN64:/ami/sw/lib64/python2.4/site-packages:/ami/sw/packages/EMAN64/lib:

The error points to /home/acheng/myami/leginon/sinedon/data.py which does not exist since I didn't put any
soft link or folder called sinedon under leginon. The sinedon it should access is under /home/ahceng/myami directly.

I removed the /home/acheng/myami/leginon from my PYTHONPATH, then the script ran.

Maybe python got confused where sinedon is when called through other packages.
