# Start with pre-processed Space Ranger output files

Space Ranger output files are pre-processed 10x Genomics Visium data. The steps covered here will show you how to import and continue analyses with this pre-processed data from the Space Ranger pipeline. Partek Flow refers to this high cellular resolution data as *Single cell counts*; each point (spot) can be 1-10 cell resolution depending on the tissue type\*.

## Add files to the project

The project includes [Human Colon Cancer (Replicate 1)](https://www.10xgenomics.com/resources/datasets/visium-cytassist-gene-expression-libraries-of-post-xenium-human-colon-cancer-ffpe-using-the-human-whole-transcriptome-probe-set-2-standard) and [Human Colon Cancer (Replicate 2)](https://www.10xgenomics.com/resources/datasets/visium-cytassist-gene-expression-libraries-of-post-xenium-human-colon-cancer-ffpe-using-the-human-whole-transcriptome-probe-set-2-standard) output files in one project.

* Obtain the filtered **Count matrix files** **(h5 or HDF5) files** and **Spatial outputs** for each sample

![](/files/kxY8uO3He8y85EWMq27r)

The spatial imaging outputs should be in compressed format.

* Navigate the options to select **10x Genomics Visium Space Ranger output** as the file format for input

![](/files/bqifu6SvPnMwCiz0Npms)

* Click [**Transfer files**](/partek-flow/user-manual/importing-data.md) on the homepage, under settings, or during import

Proceed to transfer files as shown below using the **10x Genomics Visium Space Ranger outputs** importer.

* Navigate to the appropriate files for each sample.

***Please note that the 10x Genomics Space Ranger output can be count matrix data as 1 filtered .h5 file per sample or sparse matrix files for each sample as 3 files (two .csv with one .mtx or two .tsv with one .mtx for each sample).***

***The spatial output files should be compressed in one .gz or zip file when uploaded to Partek Flow server. This should include these related image files: tissue\_hires\_image.png, tissue\_lowres\_image.png, aligned\_fiducials.jpg, detected\_tissue\_image.jpg, tissue\_positions\_list.csv, scalefactors\_json.json.***

***The high resolution image can be uploaded and is optional.***

Count matrix files and spatial outputs should be included for each sample. Once added, the *Cells* and *Features* values will update.

Once the download completes, the sample table will appear in the *Metadata* tab, with one row per sample.

The sample table is pre-populated with sample attributes, *# Cells*. Sample attributes can be added and edited manually by clicking *Manage* in the *Sample attributes* menu on the left. If a new attribute is added, click *Assign values* to assign samples to different groups. Alternatively, you can use the *Assign values from a file* option to assign sample attributes using a tab-delimited text file. For more information about sample attributes, see [here](/partek-flow/tutorials/creating-and-analyzing-a-project/the-metadata-tab.md).

For this tutorial, we do not need to edit or change any sample attributes.
