Here, we describe important commands and functions to store, access, and process data using Seurat v5. Before using seurat v5 I was able to do this in the following manner: alldata. Seurat(object, assay = assay, slot = slot) Indeed, the Seurat v5 has uplated many APIs, and I need some time to update scMEGA to keep them compatible. Seurat(assay = slot) Run rlang::last_trace(drop = FALSE) to see 4 hidden frames. However, I cannot successfully visualize my data when using DoHeatmap() or DotPlot() although VlnPlot() or FeaturePlot do work when I set my default assay to "RNA" . In addition, i need to manually declare function . In SeuratV4, I noticed that after running DietSeurat(), the nFeature_RNA and nCount_RNA columns in the metadata You signed in with another tab or window. Use layer argument, eg in the most_expressed_boxplot function of day1 (and others), # replace: # cts to the issue raised below: definitely a bug in function IntegrateLayers( method = FastMNNIntegration) because ran script with IntegrateLayers( method = CCAIntegration) and it worked fine. I can use the SCTransform v2 and integration workflow to mitigate these effects. I haven't seen this issue before when I have used RunCCA on v2. Since I have integrated Seurat object from control and mutant my colnames are for I've encountered similar issue. samples consisting of Saved searches Use saved searches to filter your results more quickly I previously posted some additional info in SeuratObject github on differences between adding feature level meta data for Assay vs. Therefore, in Issue #5, I generated new codes for calculate_avg_exp() function by editing its source codes. final@version 这个version代表什么？ 【Claude-3. table<- as. “counts”, “data”, or “scale. I tried both AggregateExpression as well as Seurat:::PseudobulkExpression.

Not sure why the newline did something. data&#8221;). Dear Seurat team, I was using BPCells with Seurat v5 (in beta version) and followed the various vignettes, trying to integrate (in a stream-lined fashion) multiple 10X samples (CellRanger <v3. 0. Hello Seurat Team, and thank you for the new version! At this point, working with datasets in different layers (for example different samples) is quite cumbersome when it comes to applying different functions (seurat functions, custom functions, other packages functions), filtering, processes, plots to each sample, or when having to group and ungroup different Summary information about Seurat objects can be had quickly and easily using standard R functions. samples Then you could use write. Hi @naamama I am not part of the SingleR team but I assume you installed SingleR using the Bioconductor release. Community-provided extensions to Seurat.

Skip to content. data" but the documentation vaguely suggests by its use of ellipsis that it works for more options than just those three:. . In Seurat v5, merging creates a single object, but keeps the expression information split into different layers for integration. The specific object is the harmonized result of 2 BPCells Seurat objects created as follows: write_matrix_dir(readRDS("counts1. 1 then everything began to work normally again. The way I fixed this without digging deep into the code or finding out which package(s) needs updating/re-updating was clearing out my user libPath and rebuilt all the packages (for me, it was just Seurat, Signac, and EnsDb. Update project_query. Please continue to use Seurat v4 as suggested in the Hello, I recently encountered this problem, when trying to run fastMNN after SCTransform. 9041 (using RStudio with R version 4. So I follow your advice on this post and integrate RGC cells subset from all data again. In my script, I want to perform CellCycleScoring prior to SCT so I can regress out the cell-cycle score. In Seurat v5, we include support for the v5 assay class, which can flexibly store data in a variety of formats (including disk-backed formats). # keep cells with at I want to used sketched data to run some integrative analysis like scvi-tools, it works well, but when I extend results to the full datasets, the function ProjectData() does not work because " !

General accessor and setter functions for Assay objects. scaledata = GetAssayData(object = x, assay = assayn, slot = "scale. It has been discussed that the cell cycle regression (or other types of correction) should be done after the integration. If not proceeding with integration, rejoin the layers after merging. raw. Running SCTransform on layer: counts. We are exploring ways of allowing users to easily change cell and feature names I noticed the default layer used by FetchData in Seurat V5 (for Assay5 objects) seems to be the counts layer. ```{r merging-2, eval=FALSE, results = 'hide'} I used DietSeurat() to slim down my SeuratObject (i. This retains the scale. rds"), dir = "counts1", Hi, I used to work with libraries SeuratDisk or sceasy to convert between formats, but conversion is not working at the moment on a Seurat 5 object to annData. Do you have a branch going with any in-progress changes? I would be happy to try to contribute code as we encounter issues. I'm updating my script, which I wrote for SeuratV4 to accommodate the changes to Seurat V5. Seurat(s_obj, assay = assay, slot = slot) GetAssayData(object = object[[assay]], layer = layer) hdWGCNA does not work with Seurat v5 at this time. PS - I am a completely new user on Github and this is my first post, so any feedback would be appreciated. Instead, you should use the layers functionality; in particular, you can create split layers according to metadata or other identifiers using the split function. The order of row names in SCT scaledata is different in the raw count. 3. V5 Assay Validity. Write better code with AI Security (Seurat) counts_matrix = GetAssayData(seurat_obj, slot="counts") I previously had Seurat 4. py to follow the current advice of the seurat authors (satijalab/seurat#1717): "To keep this simple: You should use the integrated assay when trying to 'align' cell states that are shared across datasets (i.

In an effort to keep our Issues board from getting more unruly than it already is, we’re going to begin closing out issues that haven’t had any activity since the release of v4. A vignette about moving and sharing Seurat objects would Thanks for using Seurat! It appears that this issue has gone stale. Seurat is an R toolkit for single cell genomics, developed and maintained by the Satija Lab at NYGC. It turns out that the Layer "data" had moved from the Assay "RNA" to the Assay "SCT_Reg" which I generate using SCTransform(). New data must have the same cells in the Hi, Thank you for the great tool.
