What type of mass-spec datasets can Tesorai Search process?

The current model version of Tesorai Search can support DDA datasets. The team is currently evaluating models that can also support TMT and DIA datasets. Provide your email address here [scroll to bottom of the page to subscribe to our newsletter] to be notified for when an early launch of those models are ready to be tested. Our goal is to be instrument agnostic. We tested our algorithm on TimsTOF data, and found similar or better results than the algorithms used to search the TOF data (i.e., MSFragger). An interesting note is that the model has not yet been trained or optimized on TimsTOF data and yet still works fairly well. We will be releasing an optimized (Tims)TOF and TMT model soon. Sign up for updates on pending release/soft launch dates.

What is the processing time for a given dataset?

The processing time for a dataset in Tesorai Search depends on several factors, including the raw file sizes, the number of spectra in the raw files, the number of proteins in the fasta file, and the digestion enzyme used. However, Tesorai Search leverages the power of cloud computing, which allows us to dynamically allocate resources based on the demand. This means that as your dataset grows or as more complex queries are executed, our system can scale the processing power to match, ensuring consistent performance.

Estimation Guidelines (using standard fasta files):

Small datasets (up to 10 raw files): 40 minutes
Medium datasets (10 to 100 raw files): 45 minutes
Large datasets (over 100 raw files): 1 hour (for example, we recently processed 500 raw files in under 50 minutes)

We understand the importance of efficiency in data processing and continuously work to improve the performance of Tesorai Search. Should you have specific requirements or need more detailed information, our technical support team is available to provide assistance and discuss how we can best meet your needs.

What if I have very large fasta files?

We currently limit the fasta file size to 100 MB. This is temporary as we continue to expand our computational framework. If you have a larger file or specific requirements that exceed this limitation, we encourage you to reach out to us directly.

How many raw files can I upload and process?

Tesorai Search does not limit the number of files you can upload and process. You have the flexibility to upload and process as many files as you need. However, there is a size limit of 5 GB per individual file; note that this is temporary as we continue to expand our computational framework. If you have larger files or specific requirements that exceed this limitation, we encourage you to reach out to us directly.

How often will I need to update the software?

Software updates will be automatic; we’ll be adding features continuously. We welcome your feedback as we release new versions, and suggestions for new features that would further improve your experience.

How long does it take to upload raw files to the server?

The time it takes to upload data to Tesorai Search generally depends on a few key factors, including the size of the files you are uploading and the current internet conditions. While the actual upload speed is influenced by your internet bandwidth, our platform is optimized to handle uploads as efficiently as possible. For example, for a dataset with 5 files and 1 Gb in size each, and on a typical 50 Mbps upload internet speed, the data upload would only take a couple of minutes.

How do I install Tesorai Search?

No need for installation; Tesorai Search is web-based, unlike many other tools that require installation and frequent updates on workstations. If your organization requires an on-prem solution, please reach out to info@tesorai.com.

Can I use Tesorai Search to identify protein modifications?

Yes – the current version can help identification of protein modifications, as long as they’re included in the search fasta file. The standard, sample-preparation modifications such as cysteine carbamylation, methionine oxidation, deamidation, and acetylation are also supported by default. Other PTMs, such as phosphorylation, ubiquitination, glycosylation and more are being added as we speak and will become available soon. White paper coming soon.

How much time is needed to get onboarded and trained on the system?

Onboarding and training with Tesorai Search is designed to be straightforward and quick, ensuring you can start leveraging our tool with minimal delay. Unlike other programs that can be difficult to install and configure, Tesorai Search is a cloud-based platform with a user-friendly interface featuring simple drag-and-drop functionality.

What type of use cases does Tesorai Search do especially well on?

The algorithm behind Tesorai Search is trained and evaluated on a variety of data types, and works with different instrument manufacturers (note: the beta version only supports upload of Thermo raw files, but options to upload raw files from other MS vendors will be available soon. Tesorai Search also works with several digestion enzymes and unspecific digestion (i.e., immunopeptidomics), collision energies, and fragmentation types. The model performs well on standard, single-species datasets as well as more complex meta-proteomics studies.

What are examples of types of industry applications for Tesorai Search?

Tesorai Search and Tesorai Refine can both advance research efforts in pre-clinical drug development and protein characterization of drug development, including target discovery, toxicity prediction, biomarker discovery, etc. We also work with biotech/pharma partners with customized models and service engagements – contact us to learn more. Moreover, our tool is not limited to human samples, and we’d welcome use with other species and applications beyond healthcare and human biology, including for agriculture or wastewater analysis.

How are Tesorai Search results different from results of other models?

Mass spectrometers collect a massive amount of spectral data but the majority of those mass spectra remain unidentified or unannotated - current algorithms can fail to identify up to 80% of tandem spectra. Tesorai Search leverages the most recent AI advances to enable users to increase identification of peptides and analytes in their samples despite these challenges. Other tools, such as Percolator, have also attempted to leverage other machine learning approaches for rescoring, boosting peptide and protein identification rates. But the results from recent tools that rely on boosting rates with the use of Percolator come at a cost, as they are trained to separate the targets from the decoys, which can lead to inaccurate control of the false-discovery rate [Freestone et al].

In contrast, Tesorai Search increases peptide identification without needing Percolator. Our advanced approach to peptide-spectrum matching is based on a pre-trained large deep learning model which does not utilize decoys during training and does not require training a new model for every new sample. We trained the Tesorai model on over 100M real peptide-spectrum pairs and demonstrate that the approach performs robustly across a wide range of use-cases including standard trypsin-digested human samples, immunopeptidomics, and metaproteomics, single-cell and isobaric-labeled samples. In addition to providing robust FDR control, our method increases identifications by 20% or more compared to other advanced methods.
