bold2target transforms applied in incorrect order to boldref, mask, t2star map

[madisoth]

What happened?

In a subject processed with --output-spaces MNI152NLin6Asym:res-2, the MNI-space boldref, t2star, and BOLD mask volumes appear misregistered to the MNI template, though the BOLD timeseries appear correctly registered. No errors in processing reported

Additional information / screenshots

from the command.txts in the work dir, it looks like xfms are being passed in the opposite of the expected order for antsApplyTransforms:

antsApplyTransforms --default-value 0 --dimensionality 3 --float 1 --input /wd/fmriprep_0_0_wf/sub_XXXXXX_wf/bold_ses_1_task_rest_run_01_echo_1_wf/bold_native_wf/bold_t2smap_wf/t2smap_node/T2starmap.nii.gz --interpolation LanczosWindowedSinc --output T2starmap_trans.nii.gz --reference-image /home/feczk001/tmadison/.cache/templateflow/tpl-MNI152NLin6Asym/tpl-MNI152NLin6Asym_res-02_T1w.nii.gz --transform /output_dir/sub-XXXXXX/ses-1/func/sub-XXXXXX_ses-1_task-rest_run-01_from-boldref_to-T1w_mode-image_desc-coreg_xfm.txt --transform /output_dir/sub-XXXXXX/ses-1/anat/sub-XXXXXX_ses-1_from-T1w_to-MNI152NLin6Asym_mode-image_xfm.h5

Just rewriting for readability:

antsApplyTransforms --default-value 0 --dimensionality 3 --float 1 \
    --input /wd/fmriprep_0_0_wf/sub_XXXXXX_wf/bold_ses_1_task_rest_run_01_echo_1_wf/bold_native_wf/bold_t2smap_wf/t2smap_node/T2starmap.nii.gz \
    --interpolation LanczosWindowedSinc --output T2starmap_trans.nii.gz \
    --reference-image /home/feczk001/tmadison/.cache/templateflow/tpl-MNI152NLin6Asym/tpl-MNI152NLin6Asym_res-02_T1w.nii.gz \
    --transform /output_dir/sub-XXXXXX/ses-1/func/sub-XXXXXX_ses-1_task-rest_run-01_from-boldref_to-T1w_mode-image_desc-coreg_xfm.txt \
    --transform /output_dir/sub-XXXXXX/ses-1/anat/sub-XXXXXX_ses-1_from-T1w_to-MNI152NLin6Asym_mode-image_xfm.h5

So it seems like the problem is specifically with the order of transforms in boldref2target in init_ds_volumes_wf, right?

Ah, okay. Yes, the problem is that nitransforms builds a list of transforms while antsApplyTransforms builds a stack, so we can't pass the same sequence to our own resampler versus antsApplyTransforms.
