[Camino-users] RE: subsetpoints output

[Grussu, Francesco]

Thanks for that.

However my directions do have to be part of the initial 60 direction set, regardless how  good or not it is.
This initial 60 direction set is something I was given with and I have real measures associated to it. Therefore I cannot change those.

I just wondered how to interpret the outputs of subsetpoints .

Regards
Francesco

Use Camino's point sets --- you have all the directions (well, from 3 to 256, and 755) ready for you. T
In a terminal window, do:
ls -l camino/PointSets (to obtain the full list Elec003.txt and so on).

Is this what you wanted?

Subject: [Camino-users] subsetpoints output

Dear Camino team,
I am currently trying to select a subset of 30 directions from a set of 60 directions. I would like to get the combination of 30 out of 60 directions which is the most uniform possible. Therefore,  I adopted the command subsetpoints.

My code, which I run on the input file inputDirs.bvec (a text file with 60 rows, 3 colums, one row per direction)  is something like


cat inputDirs.bvec | subsetpoints -singlesubset 30 -savestate myCurrentState > outputdirs.bvec


and after  ~ 5hours of processing, it returns the output outputdirs.bvec and a second file called orderedPoints.dat .

For what I understood from the guide, I think that both first 30 rows of orderedPoints.dat  and rows from the 2nd to 31st of outputdirs.bvec are the subset of directions I am looking for. Can you confirm this?

Overall, first 30 rows of orderedPoints.dat  and rows from the 2nd to 31st of outputdirs.bvec are the same points but ordered differently. What's the difference between the two orders?

Thanks a lot for helping me out,
all the best

Francesco
