[Swift-devel] Re: arrays of structures and building them in SWIFT

[Uri Hasson]

Hi all, thanks for the Sunday help.

I tried the simple mapper, but not go.
The short buggy SWIFT script is here:
http://www.ci.uchicago.edu/~uhasson/AFNIsnrV3.swift

The input directory contains
S05.runbyrun.reg_TS_run-1+orig.BRIK
S05.runbyrun.reg_TS_run-1+orig.HEAD
S05.runbyrun.reg_TS_run-2+orig.BRIK
S05.runbyrun.reg_TS_run-2+orig.HEAD
S05.runbyrun.reg_TS_run-3+orig.BRIK
S05.runbyrun.reg_TS_run-3+orig.HEAD

I hoped that as a result of the simple_mapper,
sruns[0].HEAD==S05.runbyrun.reg_TS_run-1+orig.HEAD
sruns[0].BRIK==S05.runbyrun.reg_TS_run-1+orig.BRIK
(I tried reading via both prefix and pattern methods in the mapper)

However, I get an error:
Execution failed:
        org.griphyn.vdl.mapping.InvalidPathException: Invalid path ([0]) for
type AFNI_obj[]

log file:
/disks/gpfs/fmri/cnari/swift/projects/uhasson/AFNIflows/SNR/AFNIsnrV3-20080504-1826-37q86081.log

Also, is there any print() or trace() command I could use to see whether
sruns was assigned the correct values?
I tried print(@filenames(sruns[0])),
print(@filename(sruns[0].HEAD))
but am not getting anything meaningful.

Best,
Uri
