A system includes a plurality of nanopore cells. Data corresponding to nanopore states of the plurality of nanopore cells is received. The data is analyzed to determine a compressed output size of the data given at least one compression technique. It is determined whether the compressed output size exceeds a data budget. In the event it is determined that the compressed output size exceeds the data budget, the data is modified. The modified data is outputted.

Adaptive compression and modification of nanopore measurement data

A method of analyzing a molecule in a nanopore is disclosed. A voltage is applied across a nanopore that is inserted in a membrane by coupling the nanopore to a voltage source. The nanopore is decoupled from the voltage source. After the decoupling, a rate of decay of the voltage across the nanopore is determined. A molecule in the nanopore is distinguished from other possible molecules based on the determined rate of decay of the voltage across the nanopore.

Nanopore-based sequencing with varying voltage stimulus

The present disclosure provides methods for processing a nucleic acid sample. For example, a method of the present disclosure may simultaneously process two populations of nucleic acid (NA) templates for two different sequencing modalities: (i) a first population comprising circularized NA templates having a size smaller than a size threshold (e.g., smaller than 2 kilobase (kb)), and (ii) a second population comprising uncircularized NA templates having a size greater than or equal to the size threshold.

Methods for processing a nucleic acid sample and compositions thereof

The present disclosure provides a method and systems for processing or analyzing a nucleic acid molecule. A method for processing or analyzing a double-stranded nucleic molecule may comprise providing the double-stranded nucleic acid molecule and a double-stranded adapter. The double-stranded adapter may comprise a nicking site within a sense strand or an anti-sense strand of the double-stranded adapter. The double-stranded adapter may then be coupled to the double-stranded nucleic acid molecule, and the double-stranded nucleic acid molecule coupled to the double-stranded adapter may be circularized to generate a circularized double-stranded nucleic acid molecule.

Methods, systems, and compositions for nucelic acid sequencing

A method of analyzing a molecule is disclosed. A voltage source is selectively connected to or disconnected from a capacitor using a switch controlled by a reset signal. A charge is stored in a capacitor when the voltage source is connected to the capacitor. The capacitor is discharged through a nanopore in a membrane when the voltage source is disconnected from the capacitor. A duty cycle of the reset signal is determined such that the voltage source and the capacitor is connected for at least a one tenth portion of a reset signal period and disconnected for a remaining portion of the reset signal period, such that a voltage across the nanopore is maintained at a higher level during the portion of the reset signal period in which the connection is maintained than during the remaining portion of the reset signal period in which the connection is not maintained.

A nanopore measurement circuit includes a first analog memory configured to store a first electrical value corresponding to a first measurement sample of a nanopore and a second analog memory configured to store a second electrical value corresponding to a second measurement sample of the nanopore. The nanopore measurement circuit also includes a measurement circuitry configured to provide an output indicating a difference between the first electrical value of the first analog memory and the second electrical value of the second analog memory.

Differential output of analog memories storing nanopore measurement samples

A system includes a circuit configured to detect a voltage corresponding to an electrical measurement of a nanopore. The system also includes a component configured to compare the voltage to another voltage. Based at least in part on the comparison, a one bit indicator is determined. The one bit indicator indicates whether the voltage indicates a change in a state of the nanopore. In the event it is determined that the voltage indicates the change in the state of the nanopore, a multiple bit signal is provided for output.

Methods, systems, and compositions for nucleic acid sequencing

A method of exporting measurements of a nanopore sensor on a nanopore based sequencing chip is disclosed. An electrical characteristic associated with the nanopore sensor is measured. The electrical characteristic associated with the nanopore sensor is processed. A summary for the electrical characteristic and one or more previous electrical characteristics is determined. The summary for the electrical characteristic and the one or more previous electrical characteristics are exported. Determining the summary includes determining that the electrical characteristic and at least a portion of the one or more previous electrical characteristics correspond to a base call event at the nanopore sensor. The summary represents the electrical characteristic and the at least a portion of the one or more previous electrical characteristics.

Exporting measurements of nanopore arrays

Diagnostic systems for sensing biological molecules are disclosed. The diagnostic systems include a fluid control delivery and control system that can be coupled to a diagnostic cartridge that includes a microfluidic device and integrated sensing electronics. The diagnostic systems can be used to sequence biological molecules.

Biomolecule diagnostic systems

A liquid voltage is applied to a first side of a lipid bilayer. The liquid voltage comprises a tag-reading period with a tag-reading voltage that tends to capture a tag into a nanopore in the lipid bilayer and an open-channel period with an open-channel voltage that tends to repel the tag. A pre-charging voltage source is connected to an integrating capacitor and a working electrode on a second side of the lipid bilayer during a pre-charging time period, such that the integrating capacitor and the working electrode are charged to a pre-charging voltage. The pre-charging voltage source is disconnected from the integrating capacitor and the working electrode during an integrating time period, such that a voltage of the integrating capacitor and a voltage of the working electrode may vary as a current flows through the nanopore. The pre-charging time period overlaps with a beginning portion of the tag-reading period.
