* Replaced vis.js for cytoscape.js to display the processing networks.
7
+
* The commands available to users, originally only filtered by input type, are now also limited by the preparation type. The options are taken from the [recommended workflows](https://qiita.ucsd.edu/workflows/).
8

* Added a new [spades](https://github.com/ablab/spades) assembly pipeline for "Genome Isolate".
9

* Fixed the following issues: [#3070](https://github.com/qiita-spots/qiita/issues/3070), [#3089](https://github.com/qiita-spots/qiita/issues/3089), [#2968](https://github.com/qiita-spots/qiita/issues/2968), [#3102](https://github.com/qiita-spots/qiita/issues/3102), and [#3079](https://github.com/qiita-spots/qiita/issues/3079).
`INSTALL.md <https://github.com/qiita-spots/qiita/blob/master/INSTALL.md>`__. However, Qiita is not designed to be used locally but rather on a server, we therefore advise against installing your own version on a personal computer. Nevertheless, it can run just fine on a laptop or small computer for development and educational purposes. For example, for every single PR and release, we install Qiita from scratch as GitHub Actions, you can follow `these steps <https://github.com/qiita-spots/qiita/actions>`__.

The following is a non-exhaustive list of features that we plan to add in the
63

future.
64

65
-
* Integration of other pipelines via artifacts. Processing of raw data in
66

external sources. For example, metabolomics processing in
67

`GNPS <http://gnps.ucsd.edu>`__ and data visualization in Qiita.
68
-
* Creation of a REST API to query and access the data hosted by Qiita.
69
-
* Improved analysis pipeline for target gene datasets.
70
-
* Crowd-sourced metadata curation of existing studies: improve the metadata of
71
-
existing studies by submitting a fix proposals to the authors of the study.

This workflow can be used for assembling (meta)-genomes (isolate and/or metagenomic data) using SPAdes v3.15.2 at set k-mer lengths of 21,33,55,77,99 and 127.

The assembled contigs are stored in per sample FASTA files (originally scaffolds.fna in SPAdes).

The --merge option merges the forward and reverse reads prior to assembly (preferable for isolate or metagenomes with high sequencing depth), the non-merge option works well for shallow shotgun data and/or complex environmental communities.

The --meta flag is used to assemble metagenomic datasets.
