Smile IDP - Isoform Detection and Prediction - new version 0.1.6

IDP is an gene Isoform Detection and Prediction tool from Second Generation Sequencing and PacBio sequencing.

It offers very reliable gene isoform identification with high sensitivity. This release includes both bug fixes and new features.

Now version 0.1.6 has been released. It offers some important additional features such as the option to use either GMAP or BLAT for long read alignment. It has also been released under the very open Apache 2.0 license.

You may find IDP here:

If you have any questions please contact us.

Release Notes:
1.) Bug fix: Now allowing computation of detected_exp_len file when not provided.
2.) estimator_choice being added to the config file and accepting
either MAP or MLE (MAP is default if the parameter is not set or
3.) Software is licensed under Apache 2.0
4.) GMAP can optionally be used as well as BLAT, however when using
GMAP, a path to the index must be specified in the config file
5.) BLAT and SeqMap are no longer bundled, paths to aligner
executables must be specified if they are not installed in the path
under their default names.

Default How to find the corresponding name of isoform name is the gene locus with an index (s

I used the software IDP to analyze iso-seq data. In the final results, I want to extract read sequences according to novel isoforms name from fasta file.
However, I can't find the corresponding transcript ID like‘ PB.1.1’ of the isoform name from IDP output results since the isoform name is the gene locus with an index (such as chr2:204193002-204296891.1).
Could you help me? I'd really appreciated that.

seqanswers lost my quick reply that had a long from answer.

basically I think you need to look in isoform.gpd output. I think you may be looking in a different file. There the known detected transcripts and genes have their appropriate names and annotations in gpd format

novel transcripts of known genes get the "chr:..." ID attached to a known gene id.

novel genes get the "chr:..." ID attached to both transcript and gene.

This behavior is sufficient for tracking whats novel. However the major caveat to all this is that IDP's calls for what is a 'novel' are VERY sensitive, and sometimes transcripts called novel may be just barely (ie 1bp) different from a known transcript. The lion's share of things that are called novel, in my experience fall into this class of VERY similar transcripts, and for most practical use require a lot of scrutiny as to whether they are really novel or not, so I recommend loading your output in UCSC genome browser to see if your novel transcripts are what you are looking for.
