I have been trying to perform alternative splicing using SUPPA2. Briefly, I have 28 human samples on which RNAseq was performed. From those, I have generated the count files with Kallisto using gencode.v44 indices. Using the same gencode.v44 gtf file, I have generated the different .ioe files for alternate splicing events. Now, my original abundance.tsv file generated by kallisto looked like this:

$ head abundance_preprocessed.tsv ENST00000456328.2 0.000000 ENST00000450305.2 0.000000 ENST00000488147.1 0.000000 ENST00000619216.1 0.000000 ENST00000473358.1 0.000000 ENST00000469289.1 0.000000 ENST00000607096.1 0.000000 ENST00000417324.1 0.000000 ENST00000461467.1 0.000000 ENST00000606857.1 0.000000 One of the generated ioe files looks like this:

So now I am trying to generate Psi results using the slurm:

!/bin/bash

SBATCH --job-name=suppa_psi_calculation

SBATCH --output=/home/achanda/%x_%j.out

SBATCH --error=/home/achanda/%x_%j.err

SBATCH --time=04:00:00

SBATCH --cpus-per-task=16

SBATCH --mem=128G

Load Python or any required modules

module load python3

Directories

SUPPA_DIR=~/software/SUPPA-2.3 EVENT_DIR=~/AS_events PROCESSED_DIR=~/Processed # Correct directory for processed files OUT_DIR=~/psi_results

Create the output directory

mkdir -p ${OUT_DIR}

Iterate over each event type

for EVENT_FILE in ${EVENT_DIR}/*.ioe; do EVENT_TYPE=$(basename ${EVENT_FILE} .ioe) # Correct extraction of the event type

# Iterate over each sample's processed file in the Processed directory
for PROCESSED_FILE in ${PROCESSED_DIR}/*_abundance_preprocessed.tsv; do
    SAMPLE_NAME=$(basename ${PROCESSED_FILE} _abundance_preprocessed.tsv)  # Correct extraction of the sample name
    OUTPUT_PREFIX="${OUT_DIR}/${SAMPLE_NAME}_${EVENT_TYPE}"

    echo "Starting processing of ${SAMPLE_NAME} for event type ${EVENT_TYPE}..."
    python3 ${SUPPA_DIR}/suppa.py psiPerEvent -i ${EVENT_FILE} -e ${PROCESSED_FILE} -o ${OUTPUT_PREFIX}

    if [ $? -eq 0 ]; then
        echo "Successfully processed ${SAMPLE_NAME} for event type ${EVENT_TYPE}."
    else
        echo "Failed to process ${SAMPLE_NAME} for event type ${EVENT_TYPE}. Check error logs for details."
    fi
done

done

However,

$ head suppa_psi_calculation_28165525.err INFO:lib.tools:File ~/Sample1_abundance_preprocessed.tsv opened in reading mode. INFO:psiCalculator:Buffering transcript expression levels. ERROR:lib.tools:1, in line 2. Skipping line... ERROR:lib.tools:2, in line 3. Skipping line... ERROR:lib.tools:3, in line 4. Skipping line... ERROR:lib.tools:4, in line 5. Skipping line...

Can someone help with what is going wrong? I can provide further details if needed.
