Hi @mtekman

Thanks for submitting your package. We are taking a quick
look at it and you will hear back from us soon.

The DESCRIPTION file for this package is:

Package: CustomGenome
Type: Package
Title: Append Custom FASTA Sequences to your Genome and Annotation Files for Downstream Mapping
Version: 0.99.0
Authors@R: 
    c(person(given="Mehmet", family="Tekman",
      email = "mtekman89@gmail.com",
      role = c("aut", "cre"), comment = c(ORCID = "0000-0002-4181-2676")),

      role = c("fnd"), comment = c(ORCID = "0000-0002-2688-9210")))
Description: CustomGenome generates a new Ensembl reference genome
    sequence and annotation files with custom FASTA sequences (e.g.
    GFP, Tomato) and produces RNA-seq count matrices with them. Genome
    reference files are fetched and validated directly from Ensembl,
    user-sequences are then appended to both, and then the new
    reference files are written to disk. Downstream analysis is then
    facilitated via Rsubread function wrappers to index the new
    reference, align user FASTA sequences to it, and then perform
    quantification for desired features (e.g. exon, utr, etc.)

Hi, I'm just providing some thoughts/comments since I was also dealing a lot with Ensembl annotations.

  1. you are downloading fasta and GTF sequences yourself from Ensembl - have you checked whether these would also be available in Bioconductor's AnnotationHub? Or, would it maybe make sense to use the BiocFileCache package for downloading/caching these resources? IMHO that would simplify this process.

The general idea to create custom annotations or add additional sequence/gene information to reference genomes is however really nice.

Hello @jorainer, thanks for the comments!

The general idea to create custom annotations or add additional sequence/gene information to reference genomes is however really nice.

Exactly, I was surprised it wasn't already a package!


AnnotationHub

Ah that's why these reviews are golden. I wish I had heard about this before I implemented the backend for Ensembl downloads that I did.

library(AnnotationHub)
ah = AnnotationHub(cache = "/my/dest/cache")
ah[ah$species == "Mus musculus" &
     ah$dataprovider == "Ensembl" &
     ah$genome=="GRCm38" &
     ah$sourcetype %in% c("GTF", "ensembl")]

The problem I'm seeing is how to pair a given genome with a given GTF file? With Ensembl this is pretty unambiguous, but with AnnotationHub I'm overwhelmed with choice.

I think this is something I will implement into the next version of this tool, since right now this is very much geared towards Ensembl downloads.


BiocFileCache

I had never heard of this, and it sounds pretty useful for some future analyses. I have some angst related to how it checks for data consistency:

https://bioconductor.org/packages/release/bioc/vignettes/BiocFileCache/inst/doc/BiocFileCache.html

bfcneedsupdate() is a method that will check the local copy of the data’s etag and last_modifed time to the etag and last_modified time of the remote resource as well as an expires time. The cache saves this information when the web resource is initially added. The expires time is checked against the current Sys.time to see if the local resource has expired. If so the resource will deem need to be updated; if unavailable or not expired will check the etag and last_modified_time. The etag information is used definitively if it is available, if it is not available it checks the last_modified time. If the resource does not have a last_modified tag either, it is undetermined. If the resource has not been download yet, it is TRUE

It sounds like it doesn't do any consistency checks with remote checksums, which is a main indicator for me on whether a large file downloaded isn't truncated. Have you had any issues with this in your code?


Also, how does BiocFileCache interact with AnnotionHub? I have the impression that AnnotationHub has it's own caching.

@lshep I'm not sure how to get around these errors. The main problem with them is that sometimes a file downloads incomplete and then the checksum fails, but sometimes this works fine (as is the case here: #3224 (comment))

What do I need to do to get this to pass, other than removing more test checks that work fine on my local devices?

@lshep

lshep commented Dec 28, 2023

Do you implement any sort of caching so that if a file works it doesnt have to be redownloaded the next time? See BiocFileCache

@mtekman

Author

mtekman commented Dec 28, 2023

I don't, but the code does check to see if the file has already been downloaded to the temp folder. I think the main issue is the sheer size of these files.

Using BiocFileCache wouldn't fix this problem if I understand correctly, since if I run this N times over N push/commits

path <- tempfile()
bfc <- BiocFileCache(path, ask = FALSE)
bfcadd(bfc, "genome", fpath="https://www.ensembl.com/big/file.fasta.gz")
bfcadd(bfc, "othergenome", fpath="https://www.ensembl.com/big/file2.fasta.gz")
## later:
mygenome1 <- bfcquery(bfc, "genome")
mygenome2 <- bfcquery(bfc, "othergenome")

it would still initialise N different independent caches and still have to initially download all files that the start of each test.

This doesn't change much from my initial code which downloads to a fixed folder for genomes and re-uses the resources over subsequent calls.

Is there anything else I can do?

@lshep

lshep commented Jan 9, 2024

If the size of the files are large then caching will be a necessity and likely a requirement by a reviewer. I would recommend a package specific directory that we general allow in cases like this. See UniProt.ws example:

    cache <- tools::R_user_dir("UniProt.ws", "cache")
    bfc <- BiocFileCache(cache, ask=FALSE)

But also be very clear to the user how much space they will need to run example data / vignettes before the start -- understanding that it can be variable once used with other data.

Hi @mtekman,

I started to review CustomGenome but it soon became clear that it needs some improvements before the review can proceed.

I always start my package review by working through the vignette, like a new user would when they encounter your package.
The current vignette has almost no evaluated code chunks, as noted by BiocCheck():

BiocCheck::BiocCheck('CustomGenome_0.99.10.tar.gz')
# Omitting some output
* Checking vignette directory...
    * WARNING: Evaluate more vignette chunks.
        10 out of 13 code chunks = 76% unevaluated
        10 non-exec code chunk(s) (e.g., '```r')
# Omitting some more output

Instead, the vignette has static copy+pasted code and output, and the problem with that is it can easily become out of sync with the actual code in the package.
Even the evaluated code chunks, like the very first one, highlight that the documentation has fallen out-of-sync with the package code:

library(CustomGenome)
data("user_sequences")
#> Warning in data("user_sequences"): data set 'user_sequences' not found

Continuing on, the next chunk contains invalid code:

homo_sap = get_genome_files(species="homo_sapiens",
                            output_folder="genomes")
#> Error in get_genome_urls(...): unused argument (output_folder = "genomes")

I corrected that error (using cache_folder instead of output_folder) and was then surprised to find that the code started downloading the genome files for Mus musculus rather than Homo sapiens!

homo_sap = get_genome_files(species="homo_sapiens",
                            cache_folder="genomes")
#> Downloading: Mus_musculus.GRCm39.105.gtf.gz                              

At this point I stopped my review because it's clear the package is not yet ready.

A few other comments from what I saw when reading the first part of the vignette:

  • The vignette must mostly comprise evaluated code chunks. I appreciate that this package needs to download and process relatively large files, so you may need to switch the examples in the vignette and documentation to smaller (or subsetted) genomes to make this feasible within Bioconductor's time and resource requirements for building and checking packages.
  • The vignette should use BiocStyle for formatting.
  • We recommend using <- rather than = for variable assignment.
  • As Lori explained, the default cache_folder value ofget_genome_files() should be tools::R_user_dir("CustomGenome", which = "cache") rather than genomes
  • The formatting in the documentation (.Rd files in the man/ directory) is a bit messy (e.g., see ?get_genome_files), which I think because the markdown formatting is incorrect in the corresponding roxygen lines in the .R files.

Please take a read of https://contributions.bioconductor.org/ to ensure that your package complies with this advice.
I'm going to mark this as 'pending pre-review changes'.
We can restart the review once you have addressed these issues and confirmed that you've read https://contributions.bioconductor.org/ to ensure that your package complies with the advice therein.

Cheers,
Pete

Hi @PeteHaitch

Thanks a lot for the review, I guess I need to work a lot on the vignette. I somehow assumed that a reproducible vignette was not a neccessity, especially for large datasets -- but I can see that I neglected it so long that it did indeed fall out of sync with the code.

Cheers to @lshep for the R_user_dir suggestion, I somehow overlooked that comment when I reimplemented the caching.

I'll get back on this soon, thanks again
