OmicSoft Suite v12.5 Release Notes

OmicSoft Suite v12.5 is now available, with several new improvements for NGS analysis and exploration of curated omics data. Check out the full details in the OmicSoft Help menu’s “Change Log”.

Download FASTQ from SRA – retrieve sample metadata from GEO simultaneously with FASTQ and SRA technical metadata downloads

With the new FASTQ download function, you can now simultaneously retrieve associated metadata from both the SRA and GEO repositories, ready to attach to your project files. The new module also supports previewing the data to ensure you chose the right project.

  • Preview GEO metadata for samples
  • Simultaneous download of GEO and SRA metadata, ready to append to analyzed samples
  • Easily append metadata to OmicData and NgsData objects

Figure 1. Preview both SRA and GEO metadata for your SRA downloads before downloading, to make sure that you are downloading the correct datasets.

Mass Spectrometry proteomics comparisons

The new Land database “ClinicalProteomicTumor” incorporates multi-omics cancer profiling studies from the CPTAC repository. These data focus on Mass Spectrometry (MS) data, but also includes RNA-seq, miRNA-seq, mutation, CNV, and methylation data.

In addition to sample-level protein expression data, you can explore statistical comparisons at the protein level, and compare differential expression patterns between protein and RNA between cohorts.

Figure 2. New MS comparisons allow deeper interrogation of proteomics datasets curated by the Omicsoft team, such as CD8+ inflamed (interferon-γ signaling) vs CD8− inflamed (platelet degranulation) tumors in clear cell Renal Cell Carcinoma (ccRCC) from PDC000127, at the RNA and protein level. (A) Differentially-regulated genes at the RNA level, calculated by DEseq2. (B) Differentially-regulated genes at the protein level, calculated by general linear model. Top up-regulated proteins were selected to illustrate concordance with RNA-level up-regulation. (C) Comparison of direction and magnitude between RNA (X-axis) and Protein (Y-axis) differential expression. Genes measured only at the RNA-level are plotted with a fold-change=0 on the Y-axis.

 

New OmicSoft Studio updater

OmicSoft Studio installer supports improved options for updating to new versions of the software.

  2. Update, delay, or turn off updates
  3. Administrators can deploy static non-updating versions to scientists

 

OmicSoft Lands API update

The latest update to OmicSoft Lands API (1.3) now supports REST interface to submit SQL queries. In addition, several improvements to query submission performance and bug fixes were addressed. Download the latest client and release notes details from my.qiagendigitalinsights.com.

OmicSoft Suite v12.4 Release Notes

OmicSoft Suite v12.4 delivers important bug fixes and improvements requested by customers.

Key improvements include:

 

Compatibility

OmicSoft Suite v12.4 components are compatible with previous OmicSoft Suite v12 components.

  • OmicSoft Server v12.4 is compatible with OmicSoft Studio v12.3, v12.2, and v12.1
  • OmicSoft Studio v12.4 is compatible with OmicSoft Server v12.3, v12.2, and v12.1
  • oshell v12.4 is compatible with OmicSoft Server v12.3, v12.2, and v12.1
  • LandExplorer v.4.3 is compatible with OmicSoft Server v12.3, v12.2, and v12.1

OmicSoft Suite v12 components are not compatible with OmicSoft Suite v11.7 or older components.

 

Retired Functionalities

  1. The BAS Server was retired starting OmicSoft Suite v12.0.
  2. OmicSoft Viewer was retired starting OmicSoft Suite v12.0, and link-sharing functionalities are removed.
  3. The legacy “Studio on the Cloud” feature has been deprecated for Studio-only users. However, OmicSoft Server supports Cloud NGS analysis with the Server on the Cloud Contact your account manager if you are interested in learning more.

 

Known issues

  1. Users cannot create mapped folder pointing to /users/ virtual subfolders
  2. If a Cloud-mapped S3 bucket contains an object '/', it will be displayed as a folder '/' that cannot be opened. Delete this folder in the S3 bucket.
  3. Users cannot search for transcripts names when creating omic data queries
  4. If updating from OmicSoft Server v12.1 or v12.2 on Windows, previous installation services must be uninstalled before the new WiX installer for OmicSoft Server Service 12.4 is installed.
  • The new WiX installer for v12.4 should be used for new installations of OmicSoft Server Service or directly updating from OmicSoft Server v12.3.
    1. Update Cloud Folder Mapping will create a new folder instead of updating the name of the existing cloud folder.
    2. On Mac OmicSoft Studio, some charts cannot be exported using Export to PowerPoint or Export to Excel
    3. After filtering and recoloring cohorts in Survival views, colors are sometimes inverted between legend and X-axis labels.
    4. RNA-seq→TMA view is visible in HPA_B37 although no samples are available with RNA-seq + TMA data; no data are displayed.
    5. Web site for ArrayExpress is not rendered properly in Add Expression Data > ArrayExpress Experiment
    6. Open in PowerPoint always opens a new PowerPoint® file; this function no longer supports appending to an open file.

OmicSoft Suite v12.3 Release Notes

QIAGEN OmicSoft Lands API expands access to curated ‘omics data

 

The new QIAGEN OmicSoft Lands API enables powerful searches across QIAGEN OmicSoft Lands data. Query data on any metadata field across Land databases, without needing to ingest data into your own SQL database.

Figure 1. QIAGEN OmicSoft Lands API schematic. Queries are submitted using SQL syntax via Python or R packages, which are processed by the QIAGEN OmicSoft Lands API query engine to find matching data within the QIAGEN curated ‘omics Land databases. Matching data are returned to the Python/R environment for analysis and visualization. Retrieved data can be downloaded as flat files or directly loaded into Python/R data frames.

Data

The QIAGEN OmicSoft Lands API provides direct access to OmicSoft’s collections of deeply-curated datasets, taking advantage of extensive controlled vocabularies and our human-centered curation approach to unlock powerful cross-project queries.

Data structure

OmicSoft’s structured tables of metadata and data can be queried on one or more fields and joined to return exactly the data needed to answer your biomarker-related questions.

QIAGEN OmicSoft OncoLand and DiseaseLand datasets have structured and curated metadata at project, sample and comparison level and are linked to ‘omics measurements for each sample, such as RNA-seq gene expression (gene, transcript, exon, junction, fusion and mutation), microarray expression (probe and gene), miRNA-seq, DNA-seq mutation calls, copy numbers and more.

Figure 2.  Schema of QIAGEN OmicSoft OncoLand and DiseaseLand datasets. Curated metadata (left) are represented within multiple tables with keys to join at the project and sample level, as well as comparisons between sample groups. Each curated data type (middle) is represented by a separate table, which can be filtered on associated metadata, data values or associated annotation (right).

Single-cell datasets within QIAGEN OmicSoft Single Cell Land databases include structured and curated metadata at project, sample, cluster, cell and comparison level, linking to gene expression (raw and normalized counts) for each cell, along with cell coordinates from pre-computed dimension reduction analyses.

Access to curated data

The initial release provides access to subscribed datasets within QIAGEN OmicSoft DiseaseLand, OncoLand and Single Cell Land databases, including the following:

 

  • 650,000+ manually curated samples
  • 1400+ diseases and 700+ tissues represented across 9000+ ‘omics projects
  • Rich harmonized metadata described across 6000+ metadata fields, allowing powerful queries to capture relevant samples across studies
  • 124,000+ comparisons from custom statistical models to reveal differentially expressed gene signatures across studies

 

API client system requirements

We offer simple-to-install clients supporting Python (Python version 3.7 or higher) and R (R version 3.6.0 or higher). These clients are used to submit SQL queries to retrieve data slices from the hosted database.

Ask your Sales Representative to add the OmicSoft Lands API to your license.
