Dear list,
in a tool I want to process a set of (bam) files. For the convenience of
the user I thought that it would be nice to allow collections as well as
manually selected files (in a param with multiple=true). Like so:
```
<conditional name="input_type">
<param name="input_type_selector" type="select" label="BAM files">
<option value="list">data set list</option>
<option value="manual">data sets</option>
</param>
<when value="manual">
<param name="input_bam" format="bam" type="data"
multiple="true" optional="false" label="BAM files" />
</when>
<when value="list">
<param name="input_bam" format="bam" type="data_collection"
collection_type="list" label="BAM files" />
</when>
</conditional>
```
Is there a way to get the number of data sets in both cases (in the
collection or selection) in a consistent way?
Currently the only way I found is:
```
#if $input_type.input_type_selector == 'manual':
#set count = len($input_type.input_bam)
#else
#set count = len($input_type.input_bam.keys())
#end if
```
Appart from this looping works like a charm:
```
#for $bam in $input_type.input_bam:
OPERATIONS...
#end for
```
Cheers,
Matthias
