The Compression Block Count value is split across two seperate fields. This change was done to increase the compression block limit to previously without extreme breakage in backwards compatability. Although the current minor version is 0x00 , a minor version greater than or equal to 0x01 is required to enable support within xLights. See xLights e33c Compression Block Count should be treated as a uint16 value, however only the lower 12 bits are used.
The upper 4 bits of the lower 12 used bits is stored as the upper 4 bits of Compression Type. As such, it is important when interpreting the Compression Type field to AND it against 0xF to ignore the upper 4 bits. The lower 8 bits are stored within the pre-existing Compression Block Count field. A software implementation should begin by reading the Compression Block values that follow the 32 byte Header. The fpp source code immediately discards any Compression Block values with a length of 0 they appear to be a product of memory alignment , leaving us with the initial 2 values.
The end address can be calculated by adding the Length value to the previously calculated start address. If no Compression Block values were read, the fpp source code will consider the file corrupted. Each uint8 within this array represents the channel state for its given index. A software implementation can seek to a specific frame by taking the product of the frame index and the length of each frame.
A controller with 4 channels indexes would have its data encoded as [4]uint8 per frame. These are especially problematic when performing analysis on cancer cell lines eg. HelaS3 or K We want to remove the effect of regions by normalizing the signal based on a non-enriched input sample. To do this, an estimate of the copy depth of all sequences is computed by running a 10kb window across the aligned input sequences in the genome and comparing the sequence depth to the mean genomic sequencing depth.
In a karyotypically normal cell line this value should be close to 1 for the entire genome. As copy number estimates for sequences increase, this value should reflect the actual sample copy number compared to the reference sequence.
The Parzen density estimates are then divided by these values to correct for differences in DNase-seq or ChIP-seq data. Ploidy directory — This directory must contain formatted. Again, we will shortly provide the script to generate these tracks.
While these will not correct specifically for copy number changes unique to a particular cell type, it will reduce other biases due to seuqnecing technologies and the DNase experiment. To generate ploidy tracks, a series of wiggle files representing ploidy information for each chromosome should be converted into our iff format using iffBuilder.
Each position should be a relative ploidy level a normal cell line would have a 1 in each position. Skip Navigation. F-Seq: A Feature Density Estimator for High-Throughput Sequence Tags Tag sequencing using high-throughput sequencing technologies are now regularly employed to identify specific sequence features such as transcription factor binding sites ChIP-seq or regions of open chromatin DNase-seq.
