mri_histo_atlas_segmen/ mri_synthseg errors (on MacBook M1 pro)
by Leon D. Lotter 12 Feb '24

12 Feb '24

External Email - Use Caution Dear FreeSurfer Developers, I am trying to run the new “NextBrain" probabilistic atlas mri_histo_atlas_segment model, which internally calls mri_synthseg with additional parameters `--threads 8 --cpu --parc --robust` as a first step. My system: MacBook Pro 2021 with M1 pro chip, currently running macOS Monterey 12.6 I installed the most up-to-date developmental FS version: freesurfer-macOS-darwin_arm64-dev-20240211-4e530af Currently, I am definitely getting stuck on the mri_synthseg step, so for now my issue is related to SynthSeg, not to the NextBrain package. This is what I did so far, assuming I am in the SUBJECTS folder: 1. The example for mri_hist_atlas_segment, `mri_histo_atlas_segment bert/mri/orig.mgz bert/mri/histo_atlas_segmentation/ 1 8` will return an error without displaying the error message. 2. I reproduced the error by running it’s analysis steps one by one: SynthSeg returns an error right after running it with any kind of configuration (e.g., `mri_synthseg --i bert/mri/orig.mgz --o mri/synthseg.mgz`): `module 'numpy' has no attribute ‘float128’. This is traceable to line 1595 of freesurfer/dev/python/scripts/mri_synthseg. The error generally seems to be a known issue on Apple chips. I fixed it with replacing `np.float128` with `np.longfloat`. 3. Now, SynthSeg starts to set itself up but quits with: ``` Node: 'model_1/unet_bn_down_0/FusedBatchNormV3' Detected at node 'model_1/unet_bn_down_0/FusedBatchNormV3' defined at (most recent call last): File "/Applications/freesurfer/dev/python/scripts/mri_synthseg", line 2642, in <module> main() File "/Applications/freesurfer/dev/python/scripts/mri_synthseg", line 162, in main predict( File "/Applications/freesurfer/dev/python/scripts/mri_synthseg", line 323, in predict post_patch_segmentation = net.predict(image) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 65, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 2554, in predict tmp_batch_outputs = self.predict_function(iterator) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 2341, in predict_function return step_function(self, iterator) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 2327, in step_function outputs = model.distribute_strategy.run(run_step, args=(data,)) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 2315, in run_step outputs = model.predict_step(data) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 2283, in predict_step return self(x, training=False) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 65, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/training.py", line 569, in __call__ return super().__call__(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 65, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/base_layer.py", line 1150, in __call__ outputs = call_fn(inputs, *args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 96, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/functional.py", line 512, in call return self._run_internal_graph(inputs, training=training, mask=mask) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/functional.py", line 669, in _run_internal_graph outputs = node.layer(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 65, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/engine/base_layer.py", line 1150, in __call__ outputs = call_fn(inputs, *args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/traceback_utils.py", line 96, in error_handler return fn(*args, **kwargs) File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/layers/normalization/batch_normalization.py", line 597, in call outputs = self._fused_batch_norm( File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/layers/normalization/batch_normalization.py", line 990, in _fused_batch_norm output, mean, variance = control_flow_util.smart_cond( File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/utils/control_flow_util.py", line 108, in smart_cond return tf.__internal__.smart_cond.smart_cond( File "/Applications/freesurfer/dev/python/miniconda3_apple_dist/py3_8_13/lib/python3.8/site-packages/keras/src/layers/normalization/batch_normalization.py", line 979, in _fused_batch_norm_inference return tf.compat.v1.nn.fused_batch_norm( Node: 'model_1/unet_bn_down_0/FusedBatchNormV3' 2 root error(s) found.

[Op:__inference_predict_function_4927] resuming program execution ``` 4. After further messing around with the mri_synthseg script, I can get past that point by changing all lines that call the `unet` function from `net = unet(nb_features=24, input_shape=[None, None, None, 1], ...)` to `net = unet(nb_features=24, input_shape=[1, None, None, None, 1], ...)` or similar (e.g. line 627, 645, 667, 684, …). However, then it crashes at a later point with other errors apparently related to data dimensionality. I would really appreciate any suggestions! I know that running the analysis on a MacBook might not be the best choice anyways, but before I try to set it up on our institute HTC (which might be a whole other challenge), I though I try it that way. Also, I figured someone might be interested in the error report. Thanks a lot! Best wishes, Leon ____________ Leon D.

by Adrian Korbecki 12 Feb '24

12 Feb '24

External Email - Use Caution Good morning, I recently came across the Bayesian Segmentation with Histological Atlas feature during my FreeSurfer research, and I'm very interested in trying it out. However, I found that my current FreeSurfer version is from June 2023, and it appears that this feature requires a version released after October 26, 2023. Could you advise on how I can obtain this newer version of FreeSurfer to utilize this module? Kind regards, Adrian Korbecki MD, PhD

make_average_subject command error
by Asuka Toyofuku 09 Feb '24

External Email - Use Caution Dear Freesurfer experts, We're trying to make an average subject for group analysis using Freesurfer 7.1, but the make_average_subject command exits with errors after calling make_average_surf: MakeAverageSurf(): 129 lh pial sphere.reg talairach.xfm 1 1 It appears to be trying to find the lh.pial surface for the first participant, but this file is named "lh.pial.T1". (In FS 5.3 and 6.0, this file was labelled "lh.pial", but with FS7.1, it seems to be named lh.pial.T1). Does anyone have a suggestion for how to fix this problem? (We want to avoid changing all the file names to "lh.pial" from "il.pial.T1") Should we call make_average_subject again with -no-surf-to-surf ? Best regards, Asuka

[TRACULA] how to setup with opposite phase-encoding
by Fahad Hannan 07 Feb '24

07 Feb '24

External Email - Use Caution Hi, I've been trying to use TRACULA on my data, trying to setup a configuration file but I am having some difficulty on how to incorporate my data. I have a DWI scan with 65 volumes (1 b0 image, 64 with b = 1000) I also have separate volumes for b0 pairs having opposite phase-encoding directions. I am not sure how to incorporate these into the configuration file. I can do it with using just the one b0 image, but I'd like to use the opposite phase-encoding as well. How would I go about this in the configuration file? Thanks, Fahad Hannan
