Abstract: Technology provided herein relates in part to methods, processes, machines and apparatuses for non-invasive assessment of genetic alterations. In particular, a method is provided for that includes obtaining a set of sequence reads. The sequence reads each include a single molecule barcode (SMB) sequence that is a non-random oligonucleotide sequence. The method further includes assigning the sequence reads to read groups according to a read group signature. The read group signature comprises an SMB sequence and a start and end position of a nucleic acid fragment from the circulating cell free sample nucleic acid. The sequence reads comprising start and end positions and an SMB sequence similar to the read group signature are assigned to a read group. The method further includes generating a consensus for each read group, and determining the presence or absence of a genetic alteration based on the consensus for each read group.

Abstract: A method for creating part images for training machine learning models, the method including: receiving a three-dimensional model of a part, wherein the part model includes physical properties of the part including weight; simulating dropping the part on a surface from a selected height and orientation; randomly placing one or more camera positions around the dropped part; rendering an image of the part model for each of the one or more camera positions; and labeling each image with part information.

Abstract: The present disclosure relates to methods for enriching circulating tumor DNA (ctDNA) to enhance early disease detection or predictions of disease progression. The present disclosure also relates to methods for enriching circulating fetal cell free DNA (fetal cfDNA) to enhance early disease detection. In some embodiments, the method comprises enriching ctDNA or fetal cfDNA in a sample by selecting for cell-free nucleic acid fragments that are less than 150 bp prior to copy number alteration (CNA) analysis. Also disclosed are compositions, systems, and computer-program products for analyzing circulating cell free nucleic acids by any of the methods disclosed herein.

Abstract: Technology provided herein relates in part to methods, processes, machines and apparatuses for determining sequences of nucleotides for nucleic acid templates in a nucleic acid sample. The technology provide herein also relates in part to methods, processes, machines and apparatuses for counting nucleic acid templates. Nucleic acid templates of a sample are tagged with nonrandom oligonucleotide adapters that include predetermined non-randomly generated sequences. The use of these nonrandom oligonucleotide adapters provides an efficient method to reduce sequencing errors, and increase the sensitivity of detection of low-frequency single nucleotide alterations.

Abstract: Technology provided herein relates in part to methods, processes, machines and apparatuses for non-invasive assessment of genomic nucleic acid instability and genomic nucleic acid stability. The method comprises providing a set of genomic portions each coupled to a copy number alteration quantification for a test sample, wherein the genomic portions comprises portions of a reference genome to which sequence reads obtained for nucleic acid from a test sample obtained from the subject have been mapped, and the copy number alteration quantification coupled to each genomic portion has been determined from a quantification of sequence reads mapped to the genomic portion; and determining, by a computing device, presence or absence of genomic instability for the subject according to the copy number alteration quantifications coupled to the genomic portions.
