Problem with TaskChainInput

[JacekHoleczek]

Hi.
let me also ask another question here.

In the "MassStorageFile" description, I find:

"namePattern" = "pattern of the file name ..."

while in the description of the "TaskChainInput", I find:

"include_file_mask" = "List of Regular expressions of which files ..."
"exclude_file_mask" = "List of Regular expressions of which files ..."

Am I really supposed to provide full-featured python "regular expressions" for the "TaskChainInput" and simple shell-like "file patterns" for the "MassStorageFile"?

For example, someting like r'.*_A_.*\.root' for the "TaskChainInput" versus '*_A_*.root' for the "MassStorageFile"?

Thanks in advance,
Best regards,
Jacek.

Hi Jacek,

This is correct - the Transform file masks take regular expression strings whereas the MassStorageFiles take Glob style file patterns. Sorry for this being confusing - I've opened another issue to attempt to make it a bit easier to use. In the meantime though, could you try with the regular expressions and see if that works?

Thanks,

Mark

Hi,
thanks for the clarification.
I ran three tests (please correct me if my "regular expressions" are not right):

1. apply only indata.include_file_mask=[ r'oa_.*_B_.*\.root' ],
2. apply only indata.exclude_file_mask=[ r'oa_.*_A_.*\.root' ],
3. apply both above properties simultaneously,
   and in all cases "trf_second" gets all 'oa_*_[AB]_*.root' files as input.
   Best regards,
   Jacek.

hi Jacek,

The copying is actually done by the Task/Transform code which isn't included in the base class (specifically the createChainUnit method in the Transform class). Are you using CoreTransform? If not, then you'll have to send me your code so I can see how this is being done as there seems to be some problems there.

Thanks,

Mark

HI,
thanks, very much, for your help.
Indeed, the Task/Transform code is "experiment specific", so I will need to talk to the original author.
For the moment you can close this issue.
Sorry for misleading.
Best regards,
Jacek.

Not a problem, please re-open the issue if we need to come back to this
