fafbseg 0.15.0

This contains substantial under the hood changes in flywire_cave_query() which may be breaking in some instances, based on fixes of my understanding of CAVE live queries.

Changes in flywire_partner_summary() are also significant in allowing considerably faster queries for multiple input neurons with cave now the default query method.

What's Changed

• flywire_cave_query(): add livelive, fix live query by @jefferis in https://github.com/natverse/fafbseg/pull/206
• Faster flywire_partner_summary() queries by @jefferis in https://github.com/natverse/fafbseg/pull/205

fafbseg 0.12.0

What's Changed

• Add support for cached flywire connectome dumps (see flywire_connectome_data() and flywire_partner_summary2() and flywire_adjacency_matrix2()) by @jefferis in https://github.com/natverse/fafbseg/pull/170

• flywire_islatest() has a cache option when using a specific version/timestamp (4b284d7d86b7e1a6da980c521a282fa693f71456). This means that flywire_updateids() and flywire_partner_summary2() can be very fast when using a fixed version.

https://github.com/natverse/fafbseg/issues?q=closed%3A2021-09-20..2021-10-29+

fafbseg 0.9.3 (pre-release version)

This is a pre-release without full release notes, principally to support a new dependant package, fancr.

• new flywire_scene() function for simple specification of flywire neuroglancer scenes.
• add a number of features to allow programmatic manipulation of neuroglancer scenes. This includes ngl_segments<-() to replace the segments in a scene +.ngscene() and -.ngscene() to add or remove segments from a scene and as.character.ngscene() to convert a scene object to a URL. See examples in ngl_segments() and ngl_decode_scene() for further details (#55, #58).
• update flywire_set_token() to support new cave and zetta tokens (for FANC dataset) (#119)
• expose chunkedgraph_token() function (#119)
• Further updates to token handling to handle FANC/FlyWire (#121)
• Private function check_cloudvolume_reticulate now supports a minimum version
• Handle 1 node neurons (#120)
• Basic support for the Python caveclient package. This enables fetching a range of annotation data from the CAVE (Connectome Annotation Versioning Engine) API including position of nuclei or user annotations. One notable improvement is more rapid fetching of synaptic partner information. This is implemented by the new method="cave" option for flywire_partner_summary() (#122).

fafbseg 0.9

The version change to 0.9 reflects some small but potentially breaking changes in user visible behaviour. In particular ngl_segments() now returns as character by default (to protect FlyWire ids, which cannot be expressed as 8 byte floating point values).

• Add flywire_latestid() function to map any (past) root id to the current root id. Specifically it it identifies the neuron inheriting the largest number of super voxels from the object specified by the input root id.
• Support for Google ffn1 20200412 segmentation (#14, #46)
• Make ngl_segments() return ids as character vector, rather than numeric, by default. Also exclude hidden ids by default (#50, #51).
• Allow ngl_segments() (and flywire_*) fns to accept URLs with surface meshes. Previously these would cause an error (#52)
• Fix ngl_encode_url() so that all tested flywire scenes can be parsed in R and then converted back to valid URLs that can be opened in flywire.ai (#53)
• Add print.ngscene method to summarise neuroglancer scenes in the console (#54)
• flywire_cloudvolume() enables improved low-level support for flywire+cloudvolume (by exposing a reusable cloudvolume object) (#48)
