Problem with mris_remiesh in recon-all
by Iglesias Gonzalez, Juan E. 12 Feb '24

Dear experts, My collaborator Martina Bocchetta is encountering a weird problem with recon-all, specifically with mris_remesh after the topology correction (see below). Any insight?

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.

Bayesian Segmentation with Histological Atlas - FreeSurfer Version
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
