flowr 0.9.10 (dates)

2016-04-18

tl;dr (summary of changes)

• Flowr Rscript gets further enhancements, taking advantage of improved funr
• run function now accepts paths.

# 'cherries' version
cd <path to pipelines>
flowr x=mypipline

# 'dates' version
flowr x=<path to pipelines>/mypipline

• Previously, flowr expected a specific structure, now using ~/.flowr.conf, one may specify their own structure - enabling flexibility.

# 'cherries' version
~/flowr
├── conf
│   ├── flowr.conf
├── pipelines
│   ├── sleep_pipe.R
├── runs

# 'dates' version (backward compatible)
~/.flowr.conf

# this file controls the location of these folders:
flow_base_path  ~/flowr
flow_conf_path  {{flow_base_path}}/conf  ## custom configuration files
flow_run_path   ~/flowr/runs  ## home of all executed flows, you may change this
flow_pipe_paths ~/flowr/pipelines,<add new paths...>

• a few bug fixes in to_flow
• several other cosmetic changes to messages

flowr 0.9.9.5 (cherries)

2015-12-03

tl;dr (summary of changes)

• Better handling of multiple flows in terms of running and re-running.
• Nicer and cleaner messages.
• Add two additional lines in flowr.conf (modules_cmds and local_cores), after upgrading the package. Everything else is compatible with previous versions.

additions/changes to flowr.conf file

• New: option local_cores, which determines (max) number of cores to use when running local jobs.

• New: flow_pipe_paths now supports multiple paths, seperated by comma. The fetch_pipes() would split the vector at commas.

• IMP: New version needs additional components in the flowr.conf file

• New: Now you can add a module_cmds variable to the config file, and this will be prefixed in all script of the pipeline. An example could be:

# version >= 0.9.8.9004
# max number of cores to use when running on a local server
local_cores 4

# default module of a pipeline
# version >= 0.9.8.9015
module_cmds ''

# examples: one may define all modules used in a pipeline here, 
# further one may specify any other command which should be run before 
# script executes.
#module_cmds    'module load samtools;export PATH=$PATH:/apps/bin'

addition/changes to status()

• New: status gets a new argument to turn off progress bar if needed.
• New enhanced get_wds/status, so that if current wd contains a flow_details file, status is shown for this folder and not sub-folder(s).

## now this works well !
flowr status x=.

addition/changes to run() and rerun() functions

• New: run function now accepts a custom configuration [conf], parameter. See help(flowr::run) for more details. This enables one, to specify custom parameters used for that pipeline.
• New: Now rerun() supports multiple folders. Basically, one may specify a parent folder which has multiple flowr runs and ask it to re-run ALL of them again, from a specific intermediate step.

• New: Flowr creates a new folder if there are multiple samples in the flowmat; basically containerizes the run, keeping the logs clean and debugging life easier.

• New: run() now supports, re-running as well. i.e. One would generate a new set of commands etc. but execute in the previous folder; possibly from a inter-mediate step (experimental feature).

other changes

• New: to_flowdef() can now guess submission and dependency types (experimental feature).
• IMP: to_flowdef now adds a parameter nodes, to enable specifying number of nodes required per-job.
• IMP: opts_flow$get replaces get_opts, for reliability etc. Also this closely follows how knitr options are set.
• fixed bugs in documentation (changed the formatting of output messages).

flowr 0.9.8 (blueberries)

2015-10-02

• Modified the output of status function, to add a status column. Specifically, this uses information from other columns and summarizes whether a specific step is pending, processing, completed or errored.

================================================================================
|                | total| started| completed| exit_status|status     |
|:---------------|-----:|-------:|---------:|-----------:|:----------|
|001.alnCmd1     |   109|     109|       109|           0|completed  |
|007.markCmd     |     3|       3|         0|           0|processing |

• [0.9.7.11]
  • Switched default value of flow@status to "created".
  • When using status on several folders, it used to be a little cluttered. Have added spaces, so that this looks prettier now.

• Introducing verbose levels:

  One can set the level of verboseness using opts_flow$set(verbose=2). Where the level may be 0, 1, 2.... Level 1 is good for most purposes, where as, level 0 is almost silent, producing messages only when neccessary. While level 2 is good when developing a new pipeline, additional details useful for debugging are provided by level 3.

• Detailed checking of flowdef

  checking if required columns are present...
  checking if resources columns are present...
  checking if dependency column has valid names...
  checking if submission column has valid names...
  checking for missing rows in def...
  checking for extra rows in def...
  checking submission and dependency types...
  jobname prev.sub_type --> dep_type --> sub_type: relationship
  1: aln1_a   none --> none --> scatter 
  2: aln2_a   scatter --> none --> scatter 
  3: sampe_a  scatter --> serial --> scatter rel: complex one:one
  4: fixrg_a  scatter --> serial --> scatter rel: complex one:one
  5: merge_a  scatter --> gather --> serial rel: many:one
  6: markdup_a    serial --> serial --> serial rel: simple one:one
  7: target_a serial --> serial --> serial rel: simple one:one
  8: realign_a    serial --> burst --> scatter rel: one:many
  9: baserecalib_a    scatter --> serial --> scatter rel: complex one:one
  10: printreads_a    scatter --> serial --> scatter rel: complex one:one

• rerun [0.9.7.9021]:
  • Previously one could specify a starting point from where a re-run flow would initiate execution. Now one may also specify an arbitary number of of steps to re-run using select and ignore; which may need to run again.
• job killing and submission now sport a progress bar:
  • |============================================================ | 70%
  • This is especially useful flows with thousands of jobs
• Fixed 2 important bugs in moab.sh, lsf.sh template file, where it was missing the -n argument.
• Now the status function has a new argument use_cache. If enabled, it skips fetching statuses of previously completed jobs; this really speeding things up.
  • Also we have added a progress bar to show the status of this summarization.

• Several detailed changes to the documentation.

flowr 0.9.7 (apples)

2015-08-22 (0.9.7.10)

• This release adds and changes functionality of several functions.
• A new function run(), creates and submits a pipeline. Specifically it follows the following steps:
  • One supplies the name of the pipeline, which is used to fetch the pipeline using: fetch_pipe()
  • create flowmat by running a function called mypipeline(), mypipeline is the name of the pipeline.
  • load configuration file, with paths to tools etc using load_conf()
  • fetch the flow definition using fetch_pipe, and load it using as.flowdef()
  • Further, create a flow object using to_flow()
  • Finally, submit to the cluster, submit_flow()
• kill(): now a S3 functions, and operates on both a flow object and flow_wd folder
• check(): Now works on flowdef and flowmat
• as.flowmat(), as.flowdef(): easy ways to fetch and check these tables
• fetch() along with fetch_pipes() and fetch_conf() simplify finding files
• Reduce function overload, moving several functions a seperate params pkg
  • moved read_sheet(), write_sheet()
  • moved get_opts(), set_opts()
  • moved .load_conf() load_conf()
