Ok, I found the problem myself. I was totally searching in the wrong
place for the error. It was simply a syntax problem. The output
definition should be like follows:
outputs
data name=output format=bed
change_format
when input=intype.bed value= format=bam/
/change_format
/data
/outputs
I was closing the data tag too early.

Hello,
I'm trying to write a wrapper for the intersectBed tool from the
BEDTools suite. The difficulty lies in the possible combinations of
input and output data formats. Input can be either bed or bam. When
the input is bed, the output is also bed. However, when the input is
bam the output can be either bam (default) or bed (by an additional
command-line switch). I cannot figure out how to dynamically set the
output format correctly. The wrapper always fails in at least one of
the three cases.
I collect the input as follows:
inputs
conditional name=intype
param name=inselect type=select label=Select input file type
option value=bed selected=trueBED, GFF/option
option value=bamBAM/option
/param
when value=bed
param name=inputBed type=data format=bed,gff label=Input A
help=Each feature in A is compared to B in search of overlaps./
/when
when value=bam
param name=inputBam type=data format=bam label=Input A
help=Each BAM alignment in A is compared to B in search of overlaps./
param name=bed type=boolean truevalue=-bed falsevalue=
checked=False label=Write output as BED help=The default is to
write output in BAM when using BAM as input./
/when
/conditional
param name=input type=data format=bed label=Input B/
/inputs
I really want to keep the conditional and the select, because the
program behaves slightly different depending on the input format.
I tried to define the output like that:
outputs
data name=output format=input/
change_format
when input=intype.bed value= format=bam/
/change_format
/outputs
However, this fails when the input is bam and I want a bed output. I
tried many different things I found in the wiki and on the mailing
list, but nothing worked properly. I'm grateful for any ideas how to
solve this problem. Thanks for your help in advance!
