Genes that have notable bias are highlighted with blue circles. Each dot is a differentially expressed gene between human and mouse in that cell type. (2016), but without gene filtering or empirical Bayes shrinkage. X axis uses the original human data and Y axis uses the denoised down-sampled human data which is denoised using SAVER-X pretrained with the paired mouse cells from La Manno et. c) Log fold changes between human and mouse data of cell-type-specific differentially expressed genes. Cell types are colored the same as in Fig.
The numbers at the right corner are the ARI for each plot. Cell labels are the computed labels from the original paper. b) t-SNE plots of the 1000 down-sampled cells for other denoising models not shown in Fig. We consider pretraining with 1907 mouse cells in the same paper, 977 original human cells, 7187 mouse cells from MCA and a total of 3344 non-UMI human developmental brain human cells. The 1000 cells in group 1 are further down sampled. 1977 human cells are randomly split into two groups. This is essential for split screen effects when you are combining 2 takes of locked-off shot and want to use different performances on each side of the frame.

Our method has great promise for denoising scanner effects in multi-study and in large-scale multi-site studies that may be confounded by scanner differences.Huang, M.
Although we did not test it here, for combining data across different scanners, LICA should prove even better at identifying scanner effects as between-scanner variability is generally much larger than within-scanner variability. Our proposed denoising method shows a greater reduction of scanner-related variance compared with standard GLM confound regression or ICA-based single-modality denoising. We utilized multi-study data to test our proposed method that were collected on a single 3T scanner, pre- and post-software and major hardware upgrades and using different acquisition parameters. In this study, we propose a novel denoising approach that implements a data-driven linked independent component analysis (LICA) to identify scanner-related effects for removal from multimodal MRI to denoise scanner effects. Unfortunately, methods to address this problem are scant. Intel GPUs and M1 Macs were not supported. GPU Requirements: NVidia or AMD GPUs with 4GB of VRAM per monitor.
These confounds reduce power and can lead to spurious findings. Adobe Premiere Pro CC 2019, 2020, 2021 Adobe After Effects CC 2019, 2020, 2021 Apple Final Cut Pro X, 10.5 - 10.6.1 Apple Motion 5.5 Magix Vegas Pro 14 - 19 Avid Media Composer 8.2 - 2021.9 Davinci Resolve 14 - 17.
However, scanner confounds hinder pooling data collected on different scanners or across software and hardware upgrades on the same scanner, even when all acquisition protocols are harmonized. Pooling magnetic resonance imaging (MRI) data across research studies, or utilizing shared data from imaging repositories, presents exceptional opportunities to advance and enhance reproducibility of neuroscience research.
